Very glad to hear and that seems wise way to look at it. At least for Mastodon, I'd think the API would get you what you need today, but hovering at 1 MM or so active users and 12 MM registered users, I could see wanting to wait till that was more like 2X or so bigger. But I would say, the demand is there. We can block servers and users there - but no good solution for sharing known sets of bad actor accounts.
