issue with IRCcloud users... setting autokick

I've been having problems with users using IRCcloud to make clones and bypass clonescanner. So im just in total blocking ALL irccloud accounts... but it doesnt want to work. what am I doing wrong?

Code:

 
On *:JOIN:#: {
if ( $wildsite == *!*@gateway/web/irccloud.com/* ) {
    /kick $chan $nick Sorry no IRCcloud users allowed :/
    msg $nick Im sorry but IRC cloud users are NOT allowed into this channel
  }
}

$wildsite is not exactly *!*@gateway/web/irccloud.com/*

yea, but the * at the end is always different thats why i cant just set one

You might want to investigate the possibilities of $istok($wildsite,irccloud.com,47).

erm.. from what i see ..what you need may be iswm operator

Code:

on *:join:#: {
if (*gateway/web/irccloud.com/* iswm $address($nick,2)) {
mode $chan +b $address($nick,2)
kick $chan $nick Sorry no IRCcloud users allowed :/
;how will you keep them out if you don't ban them? :S
 msg $nick Im sorry but IRC cloud users are NOT allowed into this channel
} 
}

P.S if this intended for a common ircd and not twitch (which is edited and weird) you can ban this > *!*@gateway/web/irccloud.com/* and it won't let any address that contains this join.
