On my server the latter has happened probably due to market board war.

First an avatar shows up standing beside me for around 5 to 10 min with the name
Suck My%Very bad word towards every female%

Then on a product a Retainer shows up with %Offensive as heck%female gamername.

So things is getting "cozy" on my server because apparently it should be only one seller on the market board and that is the Bot.

Cheers.
