To the best of my knowledge no admin/moderator would do such an act.
The next thing you need to do is change your password if you haven't yet. If someone gained access to your account, they could potentially change it again or lock you out.
If you use the same password on multiple sites, you may also have put yourself at additional risk. Someone who may have access to your account settings through another site could then use it to access additional accounts if you use the same credentials everywhere. (On this site such data is encrypted, but that might not be the case on other sites.)
