blocklists, receipts, fedi admin meta
Some reasons why blocklists *should* come with receipts:
1. So that blocks can be verified (you've probably already heard this one)
2. Resultingly, so that more people can actually *use* the blocklist without concerns about legitimacy
3. So that people can keep track of whether the issue has been resolved later
4. So that people can understand what the problematic behaviour was, and recognize it when it moves to another instance
5. So that people can see who were involved, in case those *perpetrators* move to another instance (a couple of serial account creators come to mind here)
Even if you don't personally care about verifying blocks, there are still many other reasons to keep careful track of blocking reasons.
For instance, I've seen entirely too many cases of people warning against Eris, the listener not seeing the problem and ignoring the warning, and then only finally understanding once being shown some of their posts. That only works if you keep receipts.
(That doesn't mean that there aren't people who will ignore the problem regardless of receipts; but those are not the people who will ever take it seriously anyway, they're not the target demographic here.)
blocklists (important clarification)
To clarify, since I cannot edit my original post: with "blocklist" I'm *not* referring to the defederation lists of individual instances! These are often private for good reasons.
Rather, I'm talking about the organized/collective blocklists, the ones that are meant to be used by third parties as recommendations for what to block preventatively.
