Yes, it is. I know of a case of this, and I think it is only online. The group has up to 2 hours live stream every week. They lampoon and ridicule the target, it's hard to describe. The target is a registered sex offender, so no one cares if he finds out or is bothered.

Again, it's only online as far as I know, and I don't want to identify any of them, not like I know who they are anyway. It just surprised me when I found out.
