More generally, just use Libredirect and avoid using a ton of important but shitty websites. Breezewiki in particular is fantastic, so much faster than Fandom and it’ll redirect you to a game’s actual official wiki since Fandom SEO’s itself to the top even when it has shitty misinformation and isn’t maintained.
It aleady has been. Anything, anything publicly posted and available will be harvested by, at a minimum, Google spiders. The only privacy benefits of any site can only be promises that they won’t share the information that you don’t publicly list.
And even then,.all it takes is the feds raiding a dipshit Kolektiva admin to get that information illegally anyways.
Do not organize serious actions over social media. At most, hold sensitive discussions over private, E2E encrypted chats like Matrix.
