Not trying to defend anybody here and if anyone have also noticed I always try to stay away from controversial especially those relating to my country men as obviously my judgement might be mistaken for having a soft spot for them but there are coincidence when I unintentionally use spelling that I would have seen from reading another users posts frequently so maybe since they're always writing in the same thread and they have come across each other posts more often then this might just be a coincidence. If there's no strong evidence of foul play lets not ruin people accounts just because of our gut feelings.

The evidence should be concrete and not objective before decision are taking to tag any account. @The Sceptical Chymist Kudos to you and what you have being doing in reviewing accounts on the forum (that Nigerian has been a major beneficiary of judging from their merit history) but if your generosity is being leverage on then maybe you should change the way you do the reviews, instead of individual reviews maybe you can visit the local board directly and review the posts there on Bitcoin discussion and other areas that'll be of interest to you. Hugeblack is doing that and it's helping the genuine members on the board.

Don't take my message the wrong way as I know you're entitled to how you spend your merits but I'm just giving an alternative means instead of blacklisting the community as I know matters like this might affect your judgement on the Nigerians.
