One of the wikians got hit with this same hacker around a day ago, safest option would be stop co-oping on this domain until the hacker gets banned (and hopefully doesn't come back with a different acc)

Which domain is this?

Since NA is my main and I don't want to get this happen to me

^ gt/mh domain according to the ones ive spoken to

Oh good god-

I cant even imagine how many people likely have been affected by it then, with how many people ive seen use those two sets.

I think blocking them should suffice to keep them away(?)

^^^ ohh that one

I'll make sure to avoid it then. Luckily I don't need to farm it on that account

Even if this had happened to me i would have never noticed because my damage never shows up

oh i didnt notice i was hit by it until i saw this post

ehh im never hitting over 1mil again so it doesnt matter much to me

What even is this point of this? What satisfaction do they get out of this?
