Its still possible that the original owner sold the account to ActSeller. Be that as it may I think a refund is in order. I will cover 50% of the paid price since - as Quickseller pointed out - I could possibly have prevented this by changing the mail address myself. Im not entirely sure this is true, as Im sure ActSeller changed the mail. Let me know an address where you want the BTC, PM me if you want to keep it private.
Looking at the post history it would seem that the "real" ctlaltdefeat stopped posting December 19, 2015 and then the new owner started posting February 1, 2016.
Password changes for ctlaltdefeat:
January 11, 2016 - account gets hacked?
January 25, 2016 (three times) - likely when ActSeller acquires the account
January 31, 2016 - ActSeller sells the account to Aleister Crowley
April 7, 2016 - ctlaltdefeat takes the account back via e-mail reset
ActSeller could provide more details about this, e.g. dates, any other users involved in the trade.
I only can blame the hacker and a liar , indeed I got loss. Time to post from 120 to 440+ (half of it weren't in paid sig) , wasted money to bought hacked account etc.Now Waiting for actseller clarification......
No, I dont feel Im blamed. I think a refund is in order though and Im fine covering 50% of it. As you say you already lost enough as it is even if you get a full refund.
