I manager a specific IRC and there are And there are members who curse when I block someone by ip he replaces ip And come back.
Is it possible to block by user number?

I'll give you an example of how it appears to me:


Rot_Moran is 1234567890@12.12.12.200

rot moran = Player Name
1234567890 = number of player (fixed number)
Then write his ip

My question is if have code to block entry by player number than by ip ?
