To the original poster, it's called 'poaching' - when a member from one guild attempts to convince members of another guild to leave and join theirs instead. It's a pretty low down tactic as you stated. About the only thing you can do is be more careful about who you let join and instruct your members not to accept random requests without your permission. It sucks, but bad people will do bad things.
