It's a mixed debate.
I personally am ashamed of what sK and Hearts have come to when you two fought. She's resorted to abusing her warp powers to get her and her members into the flag room. It just ruins the whole concept and is absolutely despicable. When reported to Auron or snk they don't even reply.
Also Pixel Ravenix abuses his powers to help his gang dig. They'll go to a popular digging spot, and he'll warp away anyone who comes near. His excuse when caught was "the PKers are annoying"...
Lol. There is also the unstoppable advantage that several people will abandon their gangs just to be in an admin gang.
But I find no harm in gangs like Z-Room, Arnix, Ciprioni, and Caeser that are social. (Note: I do know that Z-Room has been passed on to a normal player.)
So it's a really tricky situation.
I'd have to say no to admins owning gangs though. Because when admins are caught abusing powers to help their gangs do things, they get a small wrist slap. Even if it's their 100th time caught.
