The worst part it that their policy isn't even consistent.
For example, Twitter is extremely popular in Japan, but the "sensibilities" in Japan are different, so they have a different standard.
For example, in Japan it is completely OK to post blatant homophobic shit, and people will actually get banned for, for example, making fun of them.
I got one post deleted by twitter for "Copyright" because I took a homophobic comic in Japanese someone uploaded and changed the contents to show the stupidity of the comic.

Basically only the worst of the worst is valued by Twitter.
