Trap returning trolls in redirect to other site

[Alfa1]

It would be good to have more functions to deal with returning banned members / trolls that keep opening new accounts.

Here's a functionality request / suggestion:

Have a usergoup that is not able to log out. Members in that usergroup are automatically forwarded to a site of your choice.

This way, returning trolls could silently be moved to this usergoup. They would not be able to log out except by clearing cookies.

Logician once created a code that disallowed banned members from logging out.
