A guild in and of itself is not in control of what the other members do or do not do. HOWEVER the guild leaders ARE able to control their membership. If a guild member does something that is surely against the grain of what a guild is supposed to stand for, then said member should be booted out, period.
For myself oft a guild leader my main focus is TRUST. If we can not TRUST said member not to steal, loot from the guild's stuffs they get a very speedy tossed out on their arses. I for one am against robbing blind your own people, guild house and fellow members homes period. If a member is a thief and I do not mean in game thief I mean those that rip off their own, they do not deserve to remain in any guild I am leading, because TRUST if crucial, in that we can trust one another NOT to rip each other off, or out the door they go !
Trust is also based on honesty. So if someone ends up tellin a ton of tall tales of bs to cover their arses chances are they too get booted.
I expect folks to *man up* if they screwed up cuz that is the best way to handle whatever screw ups may have happened and also the best way to try to fix or deal with whatever issues there may be or may arise.
Sort of like having children, regardless of what they did or didn't do right or wrong, without the TRUTH ya got nothin to work with to help them or your *family* or whomever got hurt...need the truth to settle the mess !
If the member does not fit in with, just being HONEST, about their own behaviors, be they bad good or whatever chances are they won't last long in any of my guilds !
But then I am an honesty freak rl and in game soooo that is how I would run any guild I run or try to run in games too.
As far as I am concerned even the worst scum on earth should be able to admit who or what they ARE !! Ya can deal with anything if ya got a clear straight picture of any situations. BS is not what I accept ! I got probably zero tolerance for BS off folks. I will even like/tolerate, an honest
'Ima scumbag' type person, over the lyin one, any day ! lol
BE honest no matter what the heck yu are or did ...or take a hike,
as far as I am concerned as guild leader, person whatevers !!
I would take responsibility to resolve issues, or boot em, out of the guild period cuz I also would NOT wish the entire guild to be blamed for some one's lame arse actions.. I would try to resolve said issue, or boot said miscreate out ! But then I am an honesty freak. Just ask my kids rl ...don't bs me tell me the truth, level with me, OR you are in bigger trouble yet than ya think, I would tell em !

One lie and ya may be out the door for good !
