I reached Joe Gregorio’s blog today when looking around the net. And besides the nice animation, the author has a clever way to fight blog spams. I’m quoting his/her words below:
You must enter your name followed by something in parentheses, either
an email address or the URI of your web site. For example: If you
don’t enter it correctly then your comment won’t be accepted. (Hey,
it’s better than making you squint at a stupid little captcha image
trying to figure out the numbers and letters.)
Nice try. And we can have more ideas starting from this. Say asking the visiter to add 5+ space char at the end of his/her name. It’s easy for a human being, and will block most of the spammers away.
I’m currently using a black list. I think I’ll try some someday.
