UPDATE APRIL 6, 2019:I was able to reclaim my account successfully today! Thank you!

Vyg I am in a similar situation where my account was stolen. After reading similar things from others I am less optimistic than I was starting out, and I know exactly what you're going through. So far I have just messaged Cyrus, and hilariousandco, and in a weeks time will try messaging Theymos.
This is my stolen account on bitcointalk kworrom:
https://bitcointalk.org/index.php?action=profile;u=80785In the end my best advice is send one signed message with information to Cyrus/hilariousandco/Theymos, and check back every week on the situation for a message from them. If it takes longer than 6 months just move on and consider that they are choosing to ignore your request. This is at least how I am approaching the situation. Hopefully your account is returned to you, or you can find a way to eventually move on to using another account or other forums. At the very least if your account is benefiting from bounty programs like my stolen account is maybe try and contact the bounty providers to get them suspended, or again message hilariousandco to try to ban the account (hilariousandco has not responded to me yet, but said he would look at a message the other day). It is a sad state of affairs, but honestly it's just life... you will take losses and have to move on. This is unfortunately one of those situations it seems.
