heheheheheheHAHAHAHAHA you're too funny
Aahhh, needed a good laugh.
I too wish there was a good way to prevent a person from coming back, but with the use of free internet in every single starbucks, library, college campus, even bookstores now on every corner, it will be forever impossible.
One can only hope that if an individual is banned and returns, that they mend their ways and can become a productive member of the community.
Anyone of us can lie from the start. The anonyminty of the internet makes it possible for people to be who they want. Unfortunately, there's not really anything to be done about it.
Just like we have to co-exist in real life, we have to co-exist on the internet as well.
