I dunno why I made this snippet. Basically what it does is if a user joins using n00b-irc or Java IRC they get kicked and banned. This is useful if you have a channel like #scripting where you only ask scripting questions or something like that.

On *:Join:*:.ctcp $nick version
On *:ctcpreply:version:{
  if (n00b-IRC isin $1-) || (Java isin $1-) {
    kick $chan $nick You have an IRC client incompatible of mIRC scripting. Please come back with after you get mIRC at mIRC.com
    ban $chan $address($nick,2) 2
  }
}
