Account compromised, password reset.

If you mean because of password resets that we are sending, Naalis, I can only apologize for what inconvenience resetting your password may have caused you. It is not our intention to inconvenience you but to make sure that only the registered user has access to the account. The password resets happen automatically during the compromise process.

It should be noted that each password that I see, which there have been two, have been as a result of a webform submission that you sent in. When each of those submissions were processed the password was likely set.

Now if this is not as a result of the submissions that you sent in make sure you check your system.
