What is the update delay for Fediseer?
I don’t know. It’s not something I’m familiar with - it might just default to saying ‘closed’ if it doesn’t have the data.
It’s interesting that the obvious bot accounts on those instances were set up in mid-March last year, so I’m guessing that these are somebody’s army that they’ve used before, but overplayed their hand when they turned it on the DonaldJMusk person. The admins can reasonably be blamed for setting up instances with open registrations and no protections and then forgetting about them, but I’d be wary of blaming them for being behind the attack directly. The ‘nicole’ person is unlikely to have used their own instance - it’s probably just someone with the same MO as whoever owns the bots, finding and exploiting vulnerable instances.
It doesn’t, no. The bot gets its data from another bot, at https://lemmyverse.net/, which only crawls Lemmy and MBIN instances at the mo.
We’d either need to send a PR to get that bot to crawl PieFed instances too, or just replicate the functionality from the same machine that runs ‘tcbot’. Communities would also need to provide their ‘active users / month’ too. It’s just the subscriber count currently, but it shouldn’t be too much of a problem hopefully.
