Not to the regular users if “Hide modlog mod names” is enabled, but other instance admins (including remote admins) can see it all regardless. So the info itself is federated across instances.
Ex:
if I look at the /c/politics@lemmy.world modlog as a guest

if I look at the same modlog but with my lemmy.ca instance admin account


































What’s the point in reporting and helping mods if all that lead to is a ban? Let the mods handle the filth without the help of the community and see how that goes.
