If your account is on hold and you are not sure why, you can email firstname.lastname@example.org. You should have received communications from us regarding the deactivation of your account. Typically this will be because you have received three strikes on your profile, or your average rating score has dropped below 4*.
In some situations this might be a mistake or you may have extenuating circumstances that could mean you can be reactivated. Reach out to the Support Team to discuss this if you think it applies to you.
