I created a Guestbook using PHP & MySQL on my website fdiengdoh.com
from scratch but after about a few months my site got lots of useless spam post. So, first I manually deleted the post. This process become tiresome so I googled for spam checker and stumbled upon reCAPTCHA
, its a free service, so I implemented that. I got quite a reduced numbers of spam after that.
But nowadays, even after implementing reCAPTCHA also I still get lots of spam. It seem now people are spending time online to just post useless stuff on other site. Then I changed my Guestbook into a moderated Guestbook, so every post is moderated before they appear online. Its better, but I still get like 100 spam post per week.
Is there a way where I can check if the post contain 2 or more url link, then I should reject it right away. can someone show me a way to do that.
