Basically, bots entering and leaving sims are only able to do so, because they have a landing point within the sim, and since currently it is only able to be set in REGION administration, this means anyone in a mainland parcel has no chance to ever moderate scripted agents from not entering, cataloging, and recording their names, attachments, position, friends, etc. Im sure if everyone was able to simply turn on a setting that says "Must not be a scripted agent" for parcel access, we'd see far fewer tracking bots.
