• People put too much faith in admins/mods making judicious modlog actions and entries. A bad admins/mod’s word can mar you permanently because their flawed perception molds your reputation and their word is worth as much as a judicious word.
• Modlog entries are often not written thoroughly enough to give a complete story, and content being removed also removes context. This affects users’ judgment of other users.
• You can block an instance but you can’t block all of its users (without hopping to another instance that happens to be defedded from them). You have no recourse to users on another instance slandering you locally for all to see, which comes down to how the Fediverse is not just one big bubble but many overlapping smaller bubbles.
• Community/instance rules are not written clearly enough to be understood by a vast audience. A user may interpret a rule differently from a mod/admin or a rule may be obscured from the user due to the poor design. A site with a large audience like FaceBook or Reddit will have their rules written in a way that is clear to anyone, whereas Lemmy only tests rule comprehensibility on a select few.
• There are crazy mods/admins out there, and the good ones are so desperate to build the Lemmy userbase that they will maintain association with these crazy mods/admins for as long as they have to, all while the damage accrues.
• Some users treat their admin as a Messiah, and some admins treat an absurdity as a Messiah. Admins across multiple popular instances find their ideologies as an absolute guide and they will follow them to the absurd, deriving superstition and/or conspiracy paranoia that they feed to their userbase to convince them of the same. I have been forced to leave Lemmy because of an admin leading a baseless witch-hunt against me simply because I voiced disagreement with what they consider a Messiah.
• People don’t do their research about other users/mods/admins. This can turn baseless accusations into witch-hunts, or true accusations into something that is ignored in favor of assuming that a mod/admin must be judicious to hold their position. If Lemmy were to implement a removed comment/post archive, that would only help the few users who care enough about making evidence-based decisions.

You can have modlog entries against you for communities and instances that you’ve never even interacted with, and each of these are counted as individual pieces of evidence against you. You can get modlog entries against you for communities in which you’ve strictly followed the rules, and each of these are counted as individual pieces of evidence against you. You can have modlog entries against you that don’t provide any evidence — maybe you mentioned that you were of a certain demographic that an admin/mod is bigoted against so they ban you and say you did xyz crime with actually linking to a case of you committing xyz crime. Maybe you said you held a certain opinion so a mod/admin who disagrees bans you and says you committed xyz crime when you didn’t. You can do everything right and still be judged wrong.

Too many users/mods/admins put too much faith into that which lacks evidence, and even if the site were designed to give them more evidence, I doubt they would change.

I had been on Lemmy for 2 years and saw little to no headway in the infrastructure that would remedy this.
