The only tool I used enough to get an expensive one was my multi tool. Everything else is usually lost by the time I need it again, and cheap enough thats not a big deal.
Don't pick battles. You probably don't give enough of a shit about whatever xXbangedUrMum420Xx spent there entire life doing and he has nothing better to do than to win the fight. Your trolling yourself by wasting your time.
If you keep getting offended, no matter how right you are, your usually in the wrong space. Check before you move in, and block what causes you stress. You may have to move through no fault of your own, or chase out newcomers causing issues, but can't win the numbers game alone.
Without conformation, play as every bit of info as if it could be potentially lying. If it's important enough for you to care, you will have know enough to find whats true. It's almost impossible to know who's lying, shilling, or a bot. You got to verify what you read, and take the L when you half assed your fact checking.
Don't dox yourself/It's posted forever. xXbangedUrMum420Xx will swat you or send your mom your nudes over his skill issue, and is not in your legal jurisdiction.
Lurk in places you don't agree with on occasion, interact genuinely if you choose to interact. You get perspective, even if you found a bunch of paint huffing schitzos.
Be genuine, everyone can tell when its bait/BS, even if it's too late. It's a lot more fun to have a small genuine interactions than to farm engagement or upvotes.
Some one read your post, even if they didn't/can't interact.
Great, our Ai overlords are going to know I'm horny, depressed, and solve both with anime girls.
