Incorrectly classified website

Hi,

 

I'm posting here to ask how we report when a website is incorrectly classified.  Today I tried to visit this website:

 

http://www.richardsilverstein.com/tikun_olam/

 

And it was blocked because it said it was classified as a "hate" site.  I have a feeling that the way this occurred may have been a political thing but it is clearly not a hate site.

 

Thanks
