What is the best spam / abuse / malware link filtering service to reduce website links?

Question

I have two services - Lincr and LinkBunch. Lincr is a simple URL shortening service, while LinkBunch allows you to shorten multiple links to a single link. I had too much spam sent to services, so I had to close Lincr. Now even LinkBunch seems to be facing the same problem, and for that reason it is disabled by my web host.

I can’t continue to close sites like this because they have poor links, so I need a malware filtering API that I can use to filter links as they are published.

There are services that allow me to load a whole bunch of bad links to check, but instead I would rather make a direct API call on each link. What can i use for this?

Finally, what is the best malware filtering service out there?

Answer 1

Lincr does not work. On LinkBunch, where is your Captcha located?

On any site, do you limit the number of messages by IP? Do you use delay in your response? How to use hidden fields for spam (http://www.reviewmylife.co.uk/blog/2008/05/30/hidden-field-spam-trap-for-phpformmail/)?
