But that doesn't matter. Because the one who discovered this case again was me, a junior member. Maybe if someone finds DT, at least this thread will reply a lot.
In order to ban someone, you must submit a proper report to the moderators. There is a special topic on the META board. I won't point my finger at it, as I see that you are a fan of these boards, and you can do a great job with the search.
Did you create a report there? No.
In addition, for an account to be banned, clear evidence is required. I did not delve into this topic, but since you are rooting for it...
If the wallet numbers match, these are only alternate accounts. To ban an alternative account, you must provide the wallet number, for example, that first used the currently banned account, and after that, this wallet was used by the account to which you are filing a complaint about a violation of the rules.
If this is not the case, the moderators will not consider the report of either the beginner or the legend.
