What happens if a ban evader has several high ranking alt-accounts and uses them to support the ban evaders application for having the ban overturned? Even if it not related to a scam, surely in that scenario action should taken across all accounts if they are discovered.
I want to clarify if I'm not supporting ban evader, but I don't know why you can think the account will cause a further harm to the forum. It's more like your own assumption rather than being objective about what he had done in this forum.
