Looking through the writefreely.org instances on their website, a lot of the links are dead or closed for registration. The one that is open and working is promoting a paid version. Is hosting a writefreely instance heavy on resources, attracting the wrong people or just not “cool” enough?
Easy to run, but for some reason it attracts a lot of spammers if you have open registration.
Ah, that’s what my guess was. It couldn’t be that people just gave up on hosting it.
