Hi,
I have a sign up form that spammers/hackers are abusing with thousands of bogus sign ups per day. I need some good php security written into my sign up form to stop this from happening. Here is what I’m looking for.
-No more then 2 sign ups per IP address per 24 hours.
-No more then 25 sign ups per class b block. eg. “69.64.” per 24 hours.
-Ability to use a deny list where i can list ips and class b/c blocks of ips to deny permanently.
Will adding a better captcha like http://www.captcha.net/ work better? My current one doesn’t seem to be working at all. Can hackers also get around captcha.net?
If you have any other security enhancements ideas to stop this from happening, I would be happy to hear them.
Message me if you need my website address.
Regards.
