-but I'm willing to set up a feed that will auto populate with posts (maybe a different tag? like #MHartNSFW) Idk, what do you guys think?

better to keep em separate, i think. that way the people who are exclusively lookin for nsfw dont have to scroll thru the large percentage of sfw art, and people scrolling thru the sfw tag dont get jumpscared by nsfw (even if it has the nsfw warning on it)
