It’s strange that WriteFreely has more users than Lemmy because its main “instance” (https://write.as/) is an expensive paid product. Or do most people using it self-host that software?
I think most of them selfhost the software. Few kittens purpose a writefreely instance
Thanks for the answer.
The writefreely thing seem to just be a mix of spam (just look at blog.dakloifarwa.de, the top instance) and I think the way it reports users is wrong. write.owu.one apparently has 11K active users and reports having >11K posts, but there’s not a single one on the website?
I had a conversation with the Fediverse-Observe dev and Writefreely is under a spam wave (90% of MAU are spam bots, ~15k real MAU).
Writefreely instances are for some reason spam account magnets. Those users are for sure 99% spam bots.
