I'm in the same boat. My open source chrome extension[1] has just been taken down[2] after several years of no complaints because it apparently violated content policies related to nudity and pornography. Say what? Well, I guess you could view _any_ image using my extension, including nudes. Isn't that the problem with most other extensions which could be used on porn sites, like editing cookies, etc? I've submitted it for re-review but I'm not holding much hopes.
