Can only play game using a vpn

Hello I've been having this problem since april of 2016 where I can only play using a vpn or it kicks me back to realm select screen. I've played molten/warmane off and on since 2010 and never had problems till lat year.

its not my computer (have 3 Ive tried this on), It's not my internet (used 2 different isp's since problem started)

The only way i've been able to play is using a free vpn but it's getting me banned now because moltens anti bot or whatever is pinging free vpns as someone whos advertising on the server.

here's the thread from over a year ago when it started. http://forum.warmane.com/showthread.php?t=327322
