I am working on the site that will allow users to post links. Naturally, I am concerned that some of these links might lead to pages with injection, etc.

Anyone know of a plug-in that checks the link for safety? I know of urlvoid.com, but their check takes a long time, so the user has to wait for like 5 minutes.

I am looking for a plug in that will do a check on the website that user is submitting at the time the user is submitting the link to my website.
