A pretty common convention on Reddit, started by, if I recall correctly, /r/earthporn, is that many major subreddits, like /r/foodporn and such, devoted to non-pornographic images end in "-porn", where "-porn" just means "attractive image". If you're going to be browsing images on Reddit during work hours and the issue that your boss is going to have is with you browsing a non-pornographic site that has a pornographic name, you're probably in for some explaining anyway.

EDIT: Oh, if you mean that you're objecting to tits in general being on the sub rather than reading news on /r/anime_titties, disregard.
