Sometimes I am linked to artwork marked 'mature' that I can't view and then I turn the filter off and then wonder why I browse FA with the filter on and then I browse with the filter off and then I remember why and promptly turn it back on.

I don't think anyone who draws mature artwork would be offended by this, so that's okay. Everyone's different, and I don't really care what you do.
But if you're offended, then I retroactively mean to offend you (but for a completely different reason than above).
