I was wondering if this is a global thing; in recent weeks the sign up and posting of spam has risen dramatically, it got to a point were we had to shut down posting rights of new comers and made every new forum members post to be pre approved by moderators, plus we added a 5 posts a day limit and once a member passed 5 approved posts he would be in a new user group were he can freely post.
This change made life really good for our moderators, while at first we were concerend that legitimate members would be upset that they need a moderator to be approved, we actually got a very positive feedback, it was also a nice excuse for us to get more personal with every member, after the first approved post a little private message and after the fifth posts and his "graduation" to full membership we write them now a longer private message thanking them, and i must say the average numbers of posts by new forum member actually increased now...
...do you guys experience an increase in forum spam and how do you battle it?
