Agree or disagree with the politics otherwise rampant therein, subreddits like /r/KotakuInAction seem to do a good job of cataloging some instances of this (ex. [1][2] and basically anything else in their [CENSORSHIP] tag/flair). Granted, this is likely not the best source, due to the fairly political nature of such subreddits, as well as that I haven't checked many of these to verify the accuracy of them; I just occasionally like to see what different sides of the debate(s) are up to.
