I hate threads of posts on sites like this and generally don't indulge in them, but there are apparently people who think Facebook deserves a chance to federate, moderate and be trusted with our data, so here we go.
To avoid spamming people's timelines I plan to use the "unlisted" option after the next post, so that posts only show up for people who click into the thread.
(...and then I made the first post unlisted by mistake. Power user move right there. Well, I'm not going to delete and repost it all now. Click into this post to see the thread.)
Also, I'm highly likely to mute notifications for the entire thread, and if you start sealioning or nit-picking details about individual events then get ready to be blocked, because it's not about individual events, it's about the pattern of behavior.
(Oh, and of course this isn't a definitive list of bad behavior by Facebook; it isn't even all the stuff I've personally heard about.)
