If you can ever find this power abuse, than I guess I should ban everyone whose ever had any influence over anyone.
Apparently having influence (for example, Tricky as a non-staff has plenty of influence over players) and using that influence to have others do as you please is power abuse, which is against the rules.
I understand where you mean because I'm an admin of authority, and thus have influence over other players, it's power abuse to abuse that influence, however having influence does not mean power abuse; I am not in any way forcing them to leave their guild, I am simply giving them reasons to do so, which any normal member can do, and any given person with the slightest bit of persuasiveness and possibly a bit of influence can do without power.
