While exploring the area around Aryal sim, I was the object of passive griefing, I guess I'd call it. The sim is all water protected land and there's an object on the sea bottom that starts a particle/follow attack. It's the one with the notices in French. It only appears to be initiated by proximity. It's not a big deal unless you like to sail on pristine waters and enjoy the open ocean of SL. Is there an estate manager to whom this can be reported or is the abuse report way to do it?
