Well i guess if your going to completely block somone you could do it better.

alias add .guser ignore $1
alias del .guser unignore $1
on ignore:TEXT:*:*:halt 
on ignore:JOIN:#:halt 
on ignore:QUIT:#:halt 
on ignore:ACTION:*:halt 

That just looks better in my opinion. I didnt actually check the coding or anything and im not good at guser command because i never use mircs default stuff so w/e.
