OK, so I didn't check his profile in case he listed where he's from (not that I'd believe that anyway), but do you know what country he's from and/or why he seems to have such a problem with the Nigerian community?
Well, it's only him that can perfectly state what his deal is with the Nigerian community and I checked his main profile, Black_boss and discovered he made only two reports about alts. One where he called out the @sweetness account and where he intended to shame @Dimarxist.
Blackboss knows that calling out the Nigerian community with his main account will put him in such a negative light especially with how he is trying to put out an outstanding rep and continuous badgering will only bring eyes to him hence the need to use his alt.
That's probably true, since a lot of the Nigerian members also post in the main English section and there are quite a few of them who make decent posts. OP just has a bug up his ass it seems. You know what you said is true and so does everyone else on the Nigerian board, so just let his little slight against you guys slide right off you like H2O off a duck's ass.
Seriously, he's not even enough trouble. I just think the Nigerian community have more things to worry about than to be concerned with the musings of an obviously insecure and cowardly dude who can't reconcile with the idea that hardwork and dedication really pays.
