This is all Hypothetical of course, but...
Let's say that I am a Mod on another forum
We'll call it "Fett Freaks"
And let's also say that I am just a member on another forum
We'll call it "Jango Junkies"
Ok, now lets pretend that fellow member on the "Jango Junkies" forum says things that I don't care for on the "Jango Junkies" forum, but he is also a member on the "Fett Freaks" forum.
Would I be justified to ban him from the "Fett Freaks" forum (because I am powerless on "Jango Junkies" )?
Or would I just be being a ******* & abusing my position as a Mod at "Fett Freaks" by banning him there?
