Old undeserved high-rank members will be banned or red-tagged sooner or later anyway.
I don't think so.
Bans or red tags need reasons to occur, so if they don't violate forum rules, they won't be banned or get red tags from DT members.
Even they are shitposters, and repeatedly posting shit, they won't get bans or red tags if they won't violate forum rules.
Well, from my limited observations, these members would make mistakes sooner or later, e.g., plagiarism, shitpost, pyramid quotes, etc. It's difficult to change habits, that's why many members got rekt and complain in Meta.
If you want to brag about "self-made," you could put it in your "Personal Text" field.
The reporter badge is more important IMO.
