This is bullshit, I used to use that to hide stuff like jeetposts and other stuff I didn't want to see. https://files.catbox.moe/d0rx33.png
Also unrelated but I think it's funny how not even the spammers can find a picture of a black woman who's actually tolerable to look at. Literally all of them are between 2 and 4 in 10.
The only problem I've had with "hide" is that it only works until you reload the page. Then, all the bullshit comes back. The most effective way to hide posts you don't want to see permanently is to block the people making them.
