There are mainly two reasons that may force our team to enforce a ban in your account. One reason might be that our monitoring team has probably detected a huge spike in owns, and in particular, owns for machines or challenges for which you have never actually interacted with (according to our monitoring system).
In order to lift your ban, you need to contact our team at [email protected], giving them adequate proof (writeups or notes of your own) and explanations of this irregular activity.
A second reason your account is banned is due to fraudulent activity. If you feel that this is not the case, please contact our team at [email protected] for more information.
