The Public Test Realms.
Due to how their builds of PTR work, their accounts database is outdated or simply not subjected to the same upkeep/security as the regular realms, which would make sense. (They might just not give a **** either)
Now its not tested by me, which is why its here in general CHAT. Im sure a couple of you sillys have had accounts banned, try them out and report back please.
Two of my dummy accounts are suspended so I dont really have room for getting one banned right now.
(Btw I searched the forums for "Play PTR for free" and checked the 5 pages returned. Null)
Have Fun. (If it works that is)
