Summary:Feedback/Stopping bad signatures?

Signature vandalism is difficult to trace and prevent in LiquidThreads. This is compounded by the fact that at present, when a user changes their signature, it propagates across all threads they have posted.

A few solutions have been proposed:
 * Allowing administrators to reset and lock a user's signature.
 * Resetting a signature when a user is blocked.
 * Limiting the customisability of signatures.
 * Technically limiting signature content.
 * Removing the functionality whereby signatures are automatically updated.
 * Storing the signature in the wikitext.
 * Storing the signature separately.

At present, the final option is considered more sane, but further feedback is being sought.
