Topic: "Abusing" my ISP's server with punBB!

My ISP have had a fit because apparently I'm "abusing" the MySQL server, with the following query:

| 75818 | my_username | localhost | my_databasename | Query | 12639 | Opening tables | SELECT u.*, g.*, o.logged FROM punbb_users AS u INNER JOIN punbb_groups AS g ON u.group_id=g.g_id LE |

Can somebody please help me identify whether this is a legit punbb 1.2 query?
If so where it's driven from?

I must admit my version of punbb is out of date.
I'm going to get my account suspended if I don't rectify this "abuse", arghh!

All help appreciated.
