Just received a griefing alert warning from my friend gabby Catlyn one of the managers over at the Big Bang Sex Park. Thought I would pass it along to you all.
"WARNING: If you receive an object called “[L4L]-Gestures & Walkers (Freebies) <3″, delete it at once. DO NOT Rez, or wear it! This object will rez replicating micro cubes in YOUR name filling up a sim, which could cause it to crash, inadvertently making YOU the villain and subject to banning, and/or an AR being filed. Those cubes then send the malicious freebie to other avatars in the immediate vicinity, making it a vicious cycle."
So not only does it risk crashing the sim, it does so in your name and tries to send out copies of itself. So please keep an eye out on this and pass along this information.
