If it's made by a member, it is like a post. He can post 1, he can post 94823498273497247923492394792374923742. That's how it works. If it's made by a guest (bot or something), than not even one as THEORETICALLY Captcha should stop them.
Anyway, you should try to provide a more smart feedback than attack the support/IPS...
Bravo to you! You will really get far this way! 😄
