There are potentially 3 different groups of people that may ban you for a comment. If you break a community rule, a moderator may ban you as you would expect from reddit. However, since reports also notify the admins of the community instance and the admins of the instance of the reporter, you may end up banned by an admin if they believe you are breaking an instance rule.
The modlog is great for transparency, but lemmy should also make it clear what group has banned you and why. I haven’t been banned before so I’m not sure what that process looks like currently though.
rules for thee, but not for me (lemmy.ca)
To be clear, not talking about this community, obviously 😛....
