new anti spam technique

Due to the recent complain's about elgg anti-spam capabilities...... i have been having these ideas on my mind.......
1. The issues of spammers that registered succesfully in our elgg network......
My idea...... i think implementing a capcha that verify if someone is human i.e scanning the comments before posting it ( before making the comment visible to the public) e.g after posting like 3 spamlinks.....in the wire......blog comments...... group comments...
