You are accusing bullrun2020 to abuse the merit system? I really doubt it. Although I don't know German language, I know him to be a good poster in global boards. There’s no proof of your accusation as well.
Regarding the tag, I guess it’s not a good practice kf the system. But since feedback isn’t moderated, you have no way but to mutually solve the issue.
Yeah d5000, 1miaou (apologies for spelling) and bob123 seem like different people enough imo.
I think this has been brought up before as the German board isn't so active so a lot of recent posts and recent topics get pushed to the top so threads don't get swamped very much.
