We're on the latest version (well, actually, a new update JUST came out I still need to apply). Yes, the feature that moves someone into a different group after a certain number of posts does exist. The problem is that I don't want to block people from being able to post altogether. I can setup other controls, however there is no control that limits just the ability to use the "URL" tag. I wish there was, as this would limit the ability to post a link and virtually eliminate spam's motivation. They have controls for a few other tags, which is why I do not understand why URL isn't one of the key ones they provide specific controls for. Most of the spam control features exist, but spammers are constantly finding ways around them in an automated fashion (usually all bots).
