they won’t be sent by infosec.pub directly, but other instances may send activities referencing content from infosec.pub, which will lead lemmy.ml to pull it from the source as well.
this includes for example posts and comments in lemmy.world communities, because lemmy.world will announce those to lemmy.ml.
to add to that, Lemmy currently does not handle site bans well if it’s not a home instance ban, as instances don’t keep track of which other instances have banned which users. this should get better with 1.0 though, as a PR to improve that was recently merged.
for now, there is a band-aid solution that federates community bans for all communities local to the instance the user got banned from, but that only includes communities that the user previously participated in, so they’ll still be able to participate in the local copies of other communities from the instance they’re banned from, it just won’t fully federate out.
it’s also the case for deletions without account deletions, but iirc there is some delay before it gets rewritten in the db to allow the user to undelete it for a bit of time.
they’re using my federation exporter as data source.
it’s just scraping the federation api every 5 min for each included instance and then visualizing that.
instances get added automatically once they reach a threshold of monthly active users. iirc it’s >6 mau, you could check the code to confirm.
you can find your user info in the /api/v3/site response. the /api/v3/user endpoint requires a name or person id.

you can only set a community to only allow local users, not prevent users from interacting with remote communities.
you’d have to either disable federation or set up a script to automatically remove all remote communities, but that also won’t be a per user thing, just a per instance thing.
it should cover all federated actions.
any instance admin can decide to ban you on their instance or remove your content on their instance, but unless it’s a local community or they’re mod of the community these actions won’t federate and will only apply to that specific instance.
the most useful one to look at is generally the one on the user’s home instance, as that should list all actions that federated.
instance bans currently generally don’t federate and won’t show in the modlog of your home instance, but recent lemmy versions are automatically issuing community bans for all communities on that instance that you participated in.
