I'm not going to do reversals on mere abuse.
Oh yeah finally our great "theymos"
heard my poem 
. I think we can take as " I'm going to do reversals on large scale Merit abuses" is it valid for the ANN underworld freaks too? ,who do Merit business more oftenly.
No, you should probably not interpret it as that. This was reversed because theymos was able to verify that the account was compromised.
Reversals of Merit abuse look fine at the first glance and while I read that I thought first this could be a good idea. But it's obvious that a Merit reversal of abusers will lead to nothing because all the sMerit will be given back to the same cheater and it's possible for him to spent these sMerits again, a never ending story and only more work for admins.
And thanks to OP, now we know that we have to be careful. I'm just wondering the hackers got access but OP didn't enter his login data on this phishing site. Fortunately the hackers didn't change your password.
