Restrict Thread Titles to Alpha-Numeric only

[Snowhog]

I'm looking for a MOD that restricts Thread Titles to ONLY alpha (a-z (upper/lower)) and/or numeric (0-9) characters. Why? To prevent the creation of potential SQL injection strings.

We use ZB Block on our Forum, and it's been tremendously effective in keeping spam and spammers out. However, many of our members create Thread Titles using error output (as that's the problem they want to address). Sometimes these titles can be seen by ZB Block (via external search (and on rare occasion, internal search) queries, or by Moderator/Administrator merge actions, as SQL Injection attempts.

By restricting Thread Title characters to alpha-numeric only, we avoid this potential problem.
