I am getting false positive news from some sites, please block sys-con.com

Finding news for people is great, but it for some news site it does not work good because it generates a lot of false positives. Point in case is sys-con.com which has a list of all previous speakers of their conferences at the end of each and every article they post. I happen to have a number of these speakers in my correspondence and this means I will get a lot of junk news. It would be great if you could block sys-con.com now and provide a user-specific ignore list later.
