I've noticed over time some articles that speak to an historical or anthropologic precedent for male/female relations, or those that point to parity in domestic violence, etc.-in other words, those that oppose the 'victim/perp' model- are dissapearing from the web. 

Am I getting paranoid, or are even academic articles that are considered "hate speech" being culled from the internet?  I know Google has the wherewithal and resources to do this, but the authority? Am I the only one noticing this? I'm talking peer reviewed studies, Google Scholar stuff as well as research blogs, etc.

I'd like to know if others have noticed this, and if so, how to document this?
