There was an interesting tactic to scare people by using spooky words like 700 hashtags, to try to imply scale, and then, the posts had something like a short bit of text and 20 hashtags stuck to the end, and were very repetitive.
That wasn't here. That somewhere else. Mainstream social media. That cursed place. Lol.
To be honest, it's probably not terribly hard to tackle that kind of spam... I don't know how it lasted for long.
