I performed a mass favoriting of art all all forms in which I went through multiple artists (about a dozen) and favorited many things (a few dozen things). This was because I've long noticed I've not been paying attention to all a manner of art being uploaded to FA, clean, mature, and adult, and have been spending much of my time playing games on steam.
You may notice that I don't have adult artwork in my favorites gallery though... and for a select amount of you, remember that I stated I was ceasing to favorite said things and focus on non-pornographic creations. Well, I considered that a good idea on many levels, but at the same time it did not change on occasion I looked at said things. Plus, with the ability to hide favorited content from people, it's not like I need by worrying about my privacy being invaded and being pestered by trolls. As such I've chosen to set all adult art in my favorites to being hidden, so you can still see art so long as it isn't outright pornographic, and I can at least let people know what I like of their adult works without possible problems arising.
That all said, I'm going to still be playing games on my Xbox360, Steam, and Nintendo DS alot, but I'm going to now favorite most anything I like now regardless of rating.
