No vb and img in sig yet 1 user managed to

[Matrix28]

I'm rather puzzled by this, I have been using vB for 2 years now and have always turned vb and img code off in sigs and this has always worked but today one spammy user signed up and has managed to get a large banner and link in his signature. The post in question is here: http://www.computerforums.org/showthread.php?t=7196
and check the signature of me here: http://www.computerforums.org/showthread.php?t=7106 I tried to use vb but didn't work. Anyway, how is the user doing it and what can I do to stop them?

I registered and wasn't able to get an image to show in my signature.

Find that user's profile in your Admin CP. What code (unparsed) is in their signature box?

Also, you are running an old beta version of vB3. This problem could very well be a bug in that older version. You should upgrade.

Yes I checked in the admin CP and it is unparsed.

But what is the code in their signature box?
