Chilling Tales for Dark Nights. The stories are mostly fan written but there are also some tales written by old masters. Could be Ambrose Bierce today and Lovecraft tomorrow. The stories are all narrated by other fans and voice over folks.
The quality is all over the map, however. For every MJ.R. James story (or a story done in the mode of James) and for every well written original tale, there will be five that are full of grammatical and continuity errors, murky sentence structure and complete lack of logic. I feel bad for the narrators who go ahead and read this stuff with all the errors still there. Still, a good number of chills to be had there, hence the name.
Also the sub reddit, Supershort, scary stories. 250 word stories that don't take too long to read. Again, quality varies wildly from post to post. It would be nice if folks learned the use of tense, point of view and verbs, but I guess that would take too long.
