This issue can't be ignored any longer.
Excessive shitposting really tends to ruin a lot of games here, making days (mostly D1) almost unreadable and destroys some player's motivation to play, severely dropping this site's quality at the same time.
This site has plenty of examples of games with a lot of shitposting and some without, just look at the difference.
When some players sign in games with no intention to play whatsoever, shitpost all the way through d1 and need to be policy lynched, that shows there's a big problem with the entire site, why do such players get a free pass everytime ?
I also don't think having hosts adding rules against it and modkilling shitposters wouldn't make that much of a difference in the long run, this needs to be dealt with by the staff.
We also had cases of players seeing their mistake and improving, so why doesn't the FM staff, for example, PM the known shitposters at first to just discuss about it, and if this doesn't help, take action against it, like ban them for future signups ?
