As the title says, we’ve got a lot of reports about this, and we have Rule 7 - Should we take a hardline stance of no OF/SC/links etc? Vote in the comments.
If you share quality content here, you should be able to include a link to your OF for those that want more. What I think is not ok is low effort, teaser posts with an OF link. They do not add value to the community. Want to link your OF? Make sure to contribute some OC. No reposts!.
