hmm... typically hard questions !
Well, I am not a Wateen user but a PTCL user so,
1. may WATEEN officially is looking out their servers b/c its the matter of privacy !
2. Good question - I mostly used to play on Wateen Servers & have no problem while playing up there but few gamers reported that they are unable to play on WATEEN servers.So, I think that there typical settings on servers regarding players !
3. Sorry not sure about that but I think that YES !
