glitch-soc, it is possible to hide followers counts, either instance-wide
as an admin, or as a user setting.
Hiding followers count as an admin
As an instance administrator, you can hide followers count for the whole instance, by enabling the corresponding option in Site settings.
In doing so, the client API will return
-1 instead of the actual count for every
request, for both local and remote accounts, which, in glitch-soc flavor, will
result in displaying “-” instead of the actual count:
Furthermore, it will not export followers count over ActivityPub for any local user.
Hiding followers count as a user
If the instance has not opted to hide followers count instance-wide, you can still opt in to hide your own followers count from “Preferences > Other” settings.
This will hide your own followers count from the client API and ActivityPub, but it will still display other people’s followers count.
