If I take a look at the Dutch boards, lots of s****y projects are posted there. I also see a lot of spam and discussions that, in my opinion, don't belong on Bitcointalk. Also I see a lot of bounty hunters over there, posting things you can't take serious.
Interesting. I'd always assumed that the vast majority of spamming/shitposting occurred in the English sections because most signature campaigns only pay for posts in English--and I don't visit any of the local boards so I'd have no way of knowing about any spam problems there.
I don't think the local boards need a special merit system. When you come across garbage posts, spam, or whatever, just use the "report to moderator" button as Steamtyme suggested and
hopefully if there's a moderator on the Dutch boards (I don't know anything about local board moderation) they'll take action.
Spam is a problem all over bitcointalk it seems. The merit system helps but isn't enough, and other suggestions have been proposed in Meta but nothing except for the 1-merit requirement for Newbies to reach Jr. Member rank has been implemented yet. Theymos will probably make more changes if the spamming doesn't improve (or gets worse, heaven forbid), but he's slow to act--and that's not a criticism of him. He's said that even small changes can have wide-ranging and sometimes unpredictable effects, so it's best not to implement a lot of changes all at once.
