Regex is a little advanced for people who've started out with MSL. You can match for http:// and www. to catch any kind of link. You can use $count(), which functions the same as the isin operator:

on @*:text:*:#:{
if ($count($strip($1-),http://,www.)) {
ban -ku600 # $nick 2 Whoa! $nick $+ , Don't Post links in here without permission from a mod.. Cya in 10 mins B)
}
}

Your kick message states that you want to see the offender in 10 minutes (600 seconds), which means you can use the /ban command and its -k and -u switch to kick and ban his or her type 2 address simultaneously. The @ by the text event is to make sure the client that runs the code is opped.
