You've probably already been careless by now. Most of your usernames are directly or indirectly linked to your real name via your phone number, email, etc. Unless you've done perfectly thus far on security-health, start fresh with new usernames/accounts. It's a good time to do so.
Be paranoid about linking. When you use the same email for two accounts, or the same number, or same username, or even same computer, those accounts are linked. Assume the government knows. It's fine to link your anon accounts as long as none of them link to your IRL persona.
Links are transitive. If you log into account A and B on the same computer, and accounts B and C both use the same email, then accounts A and C are linked. The longer the chain, the less likely it is that anybody is going to bother to find you.
Choose the level of paranoia that is right for what you are doing. If all you're doing is saying the n word online, nobody is going to file two subpoenas to track you down. If you're doing some serious shit, they will, and you need to be impossible to track, not just hard.

You need to buy some thing swithout linking them to your IRL persona. Most places don't accept crypto. Ideally, buy prepaid visas at a gas station with cash. If you need convenience, use privacy.com to generate digital burner cards.
NOTE: if you use privacy.com, your anonymity doesn't go veyond the power of a subpoena or two. As such, it's fine for speech but not fine for organizing praxis. Use prepaids for that. And note prepaids ARE linked to the gas station you buy them at.

Most things at this point require a phone number for registration. Use hushed.com to generate a burner number. It's $2 and you can spin a new one for another $2 whenever you need to. Don't use your real credit card.
NOTE: for almost anything, using hushed is fine. It takes two subpoenas (one to hushed, then one to privacy) to break your anonymity. If all you're doing is saying the n word online, nobody will go to the trouble. If you expect high attention, buy a physical burner with cash.

Stop fucking using gmail. Set up a private email server. A VPS can be as cheap as $2.50/mo. Hetzner is cheap, but it's (((German))). Look around for a good VPS that's hosted in the Middle-East, Russia, or China.
It takes way less tech savvy than you think to set up an email server. If you're a brainlet, ask your circle's local tech nerd to set up an email server for everyone to use. If you don't have a tech nerd, get a tech nerd, you need one.
If you're too lazy to set up a mail server, protonmail and cock.li are okayish.

VPN, obviously. Don't use the ones you've heard of like NordVPN unless it's just to pirate anime. You've heard of it for a reason. Use some obscure VPN hosted in either China or Russia. Neither are about to respond to US subpoenas anytime soon.

Communication: don't try to swear off Twitter, Discord, etc. You need them. Just be extremely conscious of the linked information and what you put on them.
Services like Telegram, Signal, etc will claim to be secure; they are not, at least not if you download them from the appstore. For lightweight stuff, they're fine. For serious stuff, you need to compile the application from the source code. It's easy to do and most have guides.
As an alternative to discord, if you're organizing a group, use a self-hosted Matrix server (aka Element. Don't worry about the difference). Again, VPSes are cheap. You can get one for like $2.50/mo. If brainlet, have the tech boy set it up.

If you're doing anything more serious than running a RW discord server, the things I've just said are insufficient. There's much more to think about. Kaczynski was caught over grammar mistakes and that was before the surveillance state existed.
There exists forces who have access to all information except that which is only in your mind. Yet don't be discouraged, your mind is a dangerous place.

For browser, I recommend Icecat or Ungoogled Chromium if you can compile it. spyware.neocities.org is a great site to use to help you find something, and it covers apps too.

And if you want to get started with Linux, don't get psyopped into Ubuntu, it's garbage. Use Arch or Debian, preferably Arch. Check out LukeSmith.

Quick note on phones, don't even bother fedposting on a phone. Use it to talk to your mates and go for a night out. You should FULLY expect that everything you say will be tracked, dont even write the n word on your phone anymore. iOS, android, doesn't matter. Just don't do it.
Turn off any sort of virtual/voice assistant shit on your phone or PC. Alexa, Siri, Ok Google, whatever the fuck it is. And even after you turn it off, don't say anything sketchy out loud near it. They are listening.

You should really be using a VPN at all times. It's 2021 and you can still be doxed by a random skid that gets your IP from a logger, all they have to do is call your ISP and get lucky. Ever had someone in a GTA lobby tell you your city? It could've been your EXACT ADDRESS. If a skid can dox you, any capable person or government can do so, too.

With AI moderation and the removal of anything against the gobohomo status quo looming, achieving basic user agency has become extremely important. Learn how to host and maintain a personal site, learn how to encrypt data, use a VPN, archive everything, learn basic opsec. However, the most important step to gaining true user agency is to work on your offline life and community. To be a truly empowered user is to not rely on the internet as a sole source of fulfillment and entertainment

The Rig Veda tells the story of the Aryan people and their immigration from the steppe into the Punjabi region of northern India and Pakistan. The first enemy the Aryans encountered upon crossing the Indus River was the Dasyu: a race of vile, dark-sknned, and harsh-spoken people who worshipped the phallus. The Dasyu's description as noseless (which can be interpreted as flat-nosed) and dark-skinned, which fits the description of a Dravidian.

According to the Rig Veda, Indra slayed the Dasyu people and tore down their cities:

[01-103] HYMN CIII. Indra. Armed with his bolt and trusting in his prowess, he wandered shattering the forts of Dasas. Cast thy dart, knowing. thunderer, at the Dasyu: increase the Arya's might and glory, Indra.

[02-020] HYMN XX. Indra. 3. To him in might the gods have ever yielded, to Indra in the tumult of the battle. When in his arms they laid the bolt, he slaughtered the Dasyus and cast down their forts of iron.

After conquering the Dasyu, the Aryans created communities in the Punjabi region, and their descendants can be found even today in the Kalashian Valleys.

As can be seen in the quotes above, Dasyu is related to Dasa, which means servant and demon. The servant definition means that after they were conquered, the Dasyu were likely among the shudra caste, which served the higher caste Aryans; even today, the higher castes in india tend to be fairer skinned than the general population.

The phallus worship and lawlessness of the Dasyu as described in the Rig Veda are congruent with the conditions of modern day india, which is led by dravidian dasyus. India is known for their poor sanitation and the Indian obsession with the phallus continues in the form of linga worship and is further observed in Pajeet's Law. Pajeet's Law states that as an online discussion grows longer, the probability of a poointheloo mentioning dravidian dicks or interracial sex approaches 1.
