I think you’re looking for something like this: https://github.com/meeb/bandcampsync

I’m currently looking for a software to host my images and I found this table quite helpful to compare features: https://meichthys.github.io/foss_photo_libraries/

That’s a cool idea. Thanks for your work!

One question: Let’s say the script defederates an instance and then the admin of that instance cleans up their database and makes sure no new bots can register. Would your script remove them from the blacklist or would I have to manually check if all instances on my blacklist are still “infested” to give them a second chance?

I think it’s actually pretty clean. Thanks to the references on the person table all related entries in the database like posts, comments, etc. also get deleted if there are any. It’s better than banning all those fake users and thereby spamming the modlog of all instances that federate with you 😅
