What's there to learn from this case?
Merit posters! When you merit, you show support.
Every supported post is one more person saved from becoming a campaign abuser and account farmer!
LOL. Given the rest of your post I have to assume you're being sarcastic here...
Based on the merit histories of the known alts, I'd say this person likely still has a few un-busted accounts that are still in signature campaigns. But because they have done a careful job of avoiding any blockchain links, I won't bother mentioning who I suspect they are for now.
Despite this person's heartfelt plea to their countrymen, they are a pathological liar, I don't buy whatever story they may have for one second. Oddly enough I did get a PM from one of them in March asking for a second chance. I said no, looks like I made the right decision.
