I would suggest that you would disallow the unsigned users/quests from making new topics in most of the forums(Classic Adventures, Megamod Help currently has those)... to remove some of the ad spam. This is getting unpleasant to see 4 ads in the "Active content in the last 24 hours" search.
I say that we should do what T.C Dale of the Imoen Romance Site has does for her forums for one year. And there is no spam there on the Imoen Romance Forum.
Before you sign on or post anything, you have to answer some Baldur's Gate questions.
I say that we should adapt what T.C DALE has done so that people who post spam cannot post anything in the Baldur's Gate Mod Forums.
Edit 1:
The reason I want this is because a spambot was able to become a member of Spellhold Studios today, so they have evolved so much that they are now people! ( So now it is like the Terminator movies! )
So we must do this if we are to save SpellHold.
Plus, a couple of years ago: 4chan members joined the Chosen of Mystra and filled the forum posts with stuff and images that makes me sick to this day and caused one of the modders there to have a nervous breakdown and he then went crazy and blasted all the other members with curse words and banned them all because they had one question.
So we must plan ahead of the Spambots and the evils of 4chan before they attack us!
