I've not decided what to do here as well, maybe my tag will be negative or just neutral and mabye the abusers will be lucky this time because DT doesn't seem to care much about the case. Of course, I reserve the right to leave a tag any time as according to our pinned forum Merit guidelines by hilariousandco, a negative tag for this abuse is "almost certainly leading to you to receive negative feedback if discovered" but we'll see. 
For now, OP hasn't replied here, especially regarding my question if I should send Haunebu a PM to give him an opportunity to clarify if he is still the original account owner (another possible abuse: buying /selling Bitcointalk Accounts).

I really don't like how Haunebu reacted when he realized he can get away with it and maybe I'll re-consider a tag if there's more evidence presented that he didn't show any guilt for meriting his Alt excessively / no sign at all, that he regrets his abuse.
