Does that get you comments too? In another thread OP said they were trying to access !audiobooks@lemmy.fmhy.ml and when I go to that community via my instance, i see the posts but no comments. And its obviously been a bit since it started syncing. Our instances arent blocked
To add to this, when you post an image it is hosted on the instance you have an account with. So your instance admins may have an issue with that. The only way to know for sure is to ask them directly. I made an alt on !lemmynsfw@lemmynsfw.com just to be safe, and it’s better to separate that stuff from your main account anyway imo.
