Hacking attempt?

[dilbert]

I got a bunch of db errors last night, they all looked something like this:
Database error in vBulletin 3.8.2:

Invalid SQL:
SHOW COLUMNS FROM vB36_user LIKE 'username';

MySQL Error : Got error 28 from storage engine
Error Number : 1030
Request Date : Tuesday, September 8th 2009 @ 12:22:16 AM
Error Date : Tuesday, September 8th 2009 @ 12:22:17 AM

Referrer : http://www.bloodbanktalk.com/forum/register.php?
IP Address : xx.xxx.xxx.xxx
Username : SitPultytiese
Classname : vB_Database
MySQL Version :

The IP addresses were from the Ukraine, the Russian Federation and a few other European countries.

Was this an attempt to hack the site, and if so, is there anything I can / should do?

Thanks

Ugh, thank you. I've contacted them.
