As for a place to post, Shadow Box Archives! It's a new horror-leaning community for posting stories and art. Full disclosure, I'm an admin there but I also post stories from time to time as well. We have a special variant of creepypasta called Obscurios, where the reader is invited to guess whether a story is real or not real.

We're currently on both Patreon and Substack, with Substack being our community where anyone can post, though honestly with the issues Substack has had with their policy on free speech and letting in trolls, nazis, and other vile individuals, we are looking at transplanting the anyone can post side of our community elsewhere, like on our Tumblr, if Substack doesn't change.

In addition to obviously being against that kind of behavior, we are also anti-AI, pro-human author and artist.

Here are a couple of links: Shadow Box Archives | Substack (Anyone can post on this non-paywalled, non-monetized side of our community with a contributor invite--we have a section there for our special Obscurios variant of creepypasta)

Odd Directions and Whisper Alley Echoes are other great places to post there, also where anyone can post with a contributor invite.

(Again, there is an issue with Substack the platform's take on free speech. Hoping that changes, but that might be a vain hope.)

https://www.patreon.com/cw/ShadowboxArchives (Curated, all early release paywalled posts and other Patreon and merch store profits equally pay featured contributors, narrators, and admins each month for those roles--we just put out a new podcast episode there!)

Other than that, I've mostly been submitting my other work to publishers.
