I don't think they are bots tbh, some actually talked to or approached me in a really friendly manner when I tried to "interview" them.

And I think they're nice enough to name themselves in a way that's so easy to know.

So, they are either multiboxers or poor (Chinese?) people paid to do it :\
RMT or not, I don't care. I'd even buy a relic weapon from my cousin if it were possible :v

Bots in this game are much more sophisticated and harder to tell imo.
