I am more worried about some dedicated reddit, or 4chan user getting angry than the feds. I'm weird with this because when I write posts I wait 2 minutes, and think how would feds interpret my posts, and is it worth posting that.
I will most likely make a mistake with my anonymity one day, but to have alts increase anonymity wouldn't you have to be good at changing your writing style?
Deleting comments early and often, switching accounts, attempting to avoid linguistic analysis [gOOdd llUCk}, revealing fake details about yourself, not linking shit you find here to your discord friends while simultaneously leaving a comment. Sounds like way too much hassle.
