I use Trello. Both for planning mods and tracking service history.
Which is true. But I and others still enjoyed the content. So I wouldn’t don’t worry about it.
I’ve had old clothes fall apart on first use after being put back into circulation. So I’d definitely recommend washing them before wearing, to help avoid any potential incidents.
The instances page on each instance shows the instances that it is federating with, and there’s a section at the bottom which shows if ilthqt instance is blocking any others.
E.g. https://lemm.ee/instances
I don’t know of any way to see if that instance is being blocked by other instances, except to visit the instances page on every instance individually. Which isnt really practical.
