Like we can control what other people do on their computers? I think at some time or another, we all have gotten fake files, it sux just as much for us, as it does for you, and for some..even more so.
There is nothing that we can do about it. Do you really think that this wont happen someplace else?? If you believe this, then I really feel that you are deluding yourself.
Its sad for me to see a member leave the community, for any reason, because I believe that each member offers a unique contribution to that community, and when they leave..we all lose.
I hope that you might take the time to reconsider your actions.
