That's a new word I learned today, "shitposters". I call them "professional nonsense talkers". It's actually a good word to describe a lot of people here (from Senior to Legendary to Hero etc).
I got to notice this practice when I got scammed out of 120,000 dollars by one of the gambling platforms that sponsors these people (the English accounts). When I came in and spoke up, I got a flag just for opening a scam accusation. A lot of them came in and opposed my flag, started posting small posts, showing clearly they've barely read the scam accusation, know little details, and copy/paste the posts of each other of the scam casino account, without any quality content. And then you see they merit each other and trust each other on some really stupid posts. That's when I started calling them "professional nonsense talkers". But it seems this is a widespread practice not only among scam casino promoters (which is most of them here)
