Gregory's Server@stefko @jakob I had the same problem, and I eventually decided against completing it because so many of the questions assumed I wasn't using my own instance.
The reason I am on my own instance _might_ be relevant to your questions though. I didn't like how casually admins would threaten or actually defederate from other instances over minor infractions (or perceived future problems) and wanted to take control of that processes.
@stefko @jakob A specific example is the number of instances that are already planning to defederate from Tumblr, when they aren't even federated yet.
