I have tried to create a new account after many years I deleted my old and only account back in 2011.

As soon as I followed the steps required, it let me know I was going through an appeal procedure (!?) due to an uncertain activity with my account (!!!) and they will let me know whether I can get an account or not...I repeat, I have tried to create a new account after many years, no idea what they are talking about!

After an hour they disabled the account and sent me an email as well.
