We know that unsubbing people doesn't work. They just come back. And there is no currently available remedy to prevent that.

However, I wonder if their is such a thing as a web site considering using a legal restraining order against an individual to prevent (by law) that person from rejoining?

Obviously it won't physically bar them from signing up again, if they want to. But it would provide the website with some kind of protection? Or a way to have that person fined? Or arrested? Or somehow punished, in a real way. Something that will enter their daily life, something that will be on file with their police department or court or county.

It would have their real name and/or isp and/or their aka/aliases.

There is even a business potential. A pay-per-access search business that would carry the records of banned users and known information that could be accessed by other isps or site administrators. It's more than the rumor mongers, so no one can start a bunch of gossip and have the person they are gossiping about show up...no, it's real legal stuff, that a site has pursued.

This also gives TOU some teeth. Fines or legal paperwork would discourage some of the people from doing what they do. Especially if they do it from work. ISPs are traceable. Tribe.net can find out what ISP you are using and notify that ISP. Just like we can notify an ISP ourselves when we get spam mail from one of their members.

Results may vary. Yahoo doesn't seem to put up with spammers. But what what if it's a business? What business account wants to find out that one of their users in their business is harassing people? That would put a stop to the usage of the internet for "personal use" at that business in many cases.

So that the offender not only effectively gets themselves blocked by their boss, so does everyone else in that business. And they won't look upon the one who is ultimately responsible (the one dumbass who harassed people) too kindly.
