Security: Check href & body parts of links

[neomenlo]

Many viruses spread by IM use deceptive URLs to trick the victim to click them.

For example, I received an IM, but I copy and pasted the location and noticed the discrepancy. The link in blue said something like:
http://photobucket.com/numbers/number.jpg
When the URL (href) went to:
http://otherwebsite.com/something.com

1: The URLs do not match

I would like to see pidgin automatically check if the urls are different, and warn the user that the link is high risk and deceptive. However, a few links are sent with a completely different body by wrapping a few words with a url.

2: The url leads to an executable

I don't think I've ever seen an executable transfered via IM protocol. So, links to executables should also bring up a warning dialog telling the risks.

This sounds like a very good plugin idea to me. Especially because the criteria for what should and should not trigger the warning can be variable in different scenarios.
