Oh wow.

I wonder if I donated, if I would use Mbin much more (according to the "after all, I put money into it so I must like it" kind of brain workings) or less ("I've contributed to Fediverse success, no need to show up and post as much").

You are an admin who is active enough to reassure me you have not disappeared, you respond quickly to instance questions on kbin.run meta, and nothing is going wrong with the instance. I think you are doing a good job, thank you!!

Ah, removing "hide nsfw content" checkmark helped. I had to miss it when setting up my profile. Thanks for your help

Hmm, do you have the "Hide NSFW content" setting enabled in your profile (picture attached)? Otherwise NSFW should load just fine. If it's a magazine that hasn't been subscribed to by any other kbin.run user, then it might take a few iterations of federation to take place before any content starts appearing after subscribing. You should see a banner at the top of the magazine warning of lack of subscribers/content if so.

The only NSFW policy I have in place is that NSFW content must be tagged 18+ and comply with all US laws.

Might be a silly question, but can you make sure the kbin.run sidebar on your end is showing subscribed? Even though Mbin shows the total subscriber count, it won't matter unless a local user is subscribed to the magazine in question for federation to take place. Also, if incremental.social is not on the latest main branch of Mbin the DMs won't federate, it'll be officially supported in the next release.

I checked fedia.io and it also is showing the last update about a week ago, leading me to believe it's an issue with incremental.social. I'd recommend using their contact form if you can find it.
