This will get you banned, and may have your IP block permanently banned or G-Lined or K-Lined or Akilled in larger networks. If you are going to send invite messages via join and part actions of channel users, be sure to either use a proxy, or a relay so that your IP will not be easily traced.
Remaining anonymous to channel operators and stealth with your invites will avoid your channel from being blacklisted by channel operators in their own channels, although this is inevitable if you are using IRC channel inviter scripts.
