The usage of this message is a (futile?) response of store and land owners to the criminal activities of those who use the Copybot (and said application is the THIRD display of irresponsibility by the libSL group). If LL actually did something against the usage of the copybot (and no, I can't see how it can have any legitimate use; neither can ANY resident), people wouldn't resort to the !quit message.
It's all YOUR fault, people. It's YOUR fault, because you simply DON'T WANT to listen to the simplest calls to common sense. It's YOUR fault, because:
1. You allow the creation of unverified accounts (making any disciplinary measures against offenders laughable, as they'll be back in seconds - not to mention that this means that many escorts in SL can VERY WELL be well under 18 years of age).
2. You allow libSL to do whatever it pleases, without having to follow ANY rules. It was libSL members who distributed - irresponsibly - the Copybot in the first place and yet you didn't do anything. Oh, and you wholeheartedly support libSL, but the TUi tutors lose their funding... Bravo.
3. You CHOSE to side with GRIEFERS, THIEVES, FREELOADERS and LAZY COPYCATS, turning your backs on the suckers called content creators, verified (and paying) members and building/scripting tutors. BRAVO.
