fast relogging or dual logging
I don't know how GMs spot dual log. The same I.P.? So they can see what character has I.P. X, what I.P. Y, etc. So, why they can't spot fast relog?
If character with name X and with I.P.=Y leaves game, then in 0-9 minutes someone log in with I.P.=Y, and character's name isn't X = fast relog = ban.
If it's impossible, then how do GMs spot dual logging?
Edit:
Or
If character with name X and with I.P.=Y leaves game, then in 0-9 minutes someone log in with I.P.=Y, and character's name isn't X = fast relog = kick from the game (auto exit).
