this snippet is to detect blaklisted channels to a user who are trying to join your protected channels. if it;s detected than users will be kick + ban from your channel. Pls be notice that such a script can only be effective if blacklisted channels do not set to +s, and if you have identical raw events like in group #visible already in your existing remote scripts, in order to avoid conflicting i suggest to remove the existing identical raw codes

;notes : if you have identical raw events like in group #visible already in your existing remote scripts, in order to avoid conflicting i suggest to remove the existing raw codes, and if you use older version than mIRC 6.16 pls replace $v1 with $ifmatch on alias thisspam
;a script like this one will only be effective if blacklisted channel doesn't set to +s that whois raw reply on a user can show all channels currently joined.
