How many New Registered Users do you have on an average day? You could always send all New User's Posts, until they have X number of Posts, to the Moderation Que and then his posts (as a New User) would never make it into the Threads.

In one of the Forums I administer, NO New Registered User's Posts appear until I approve them personally and they go into the Moderation Que until they have 3 "approved" Posts. Guests are not allowed to Post.

You can rename your 'Registered Users' usergroup to 'Newbies' (or whatever you want). To have all posts of this usergroup moderated. Set 'Follow Forum Moderation Rules' in the Usergroup -> Forum Viewing Permissions -> 'Follow Forum Moderation Rules -> No. You can then automatically move users to a second usergroup that's not moderated using a Usergroup Promotion after X posts.

So if you don't have too many New Registered Users each day, you can moderate all their new posts and this "problem" user can not keep re-registering and posting before you can catch his posts. After you have approved Three Posts (or however many you want) the "newly registered users" are automatically promoted into a non-automatically moderated status.
