What would you do?

[Leah]

What would you do if you suspected that users of your board in some way had access to read in the "adminforum"? When a group of users seem to know more than they should. By guessing or, even worse, loaning a moderators password or in another way.

Let's say it's only a "gut-feeling" because of comments made when there have been conflicts with some users. Let's say they refer to things they weren't supposed to know.

You've chosen moderators carefully and have no reason not to trust them, but still..

How would you handle it? Would you use any hacks that could help you find out for sure? What kind of hacks.
