The banning of screen names doesn't stop someone from coming back and creating a new identity.
That said, I have seen several members of this forum decide they want to get rid of their old identity and get a new forum name. I've done it, Cornerman has done it, John Barton Collins has done it, Eydie Romano has done it when she wanted to have her own name and not her husband's forum name, et cetera.
If someone has been banned one, two, maybe three times on this forum, is there a way to prevent them from creating a new identity and coming back on this forum a fourth time with a new name?
From what I understand, if you ban the IP address, you could be banning other good-standing members who use that same IP address as the "banned" one or offender, and so that doesn't work.
I am not hip to computer technology. The only way I recognize repeat offenders is their writing styles. Anyone who visited RSB NewsGroup is well aware of the multiple identity problem, a technique used by mentally/emotionally challenged individuals.
