I have to say looking at the posts there is no proof that it is a scammer, in saying that instinct tells me it is, a Bee Keeper from Nigeria would have difficulty in keeping up with the latest terminology and there is no lie about the location I would presume.
Keep a close eye and insist on those photos of the hives, ask what type of bees they keep and ask about yields, I know little about bees myself, I got stung a few times as a kid and soon discovered I dont like bees but I do like honey which is why I tolerate them
If the questions cant be answered or the photos not supplied then ban away, there is a slight chance that it is genuine in which case you may just expand your knowledge on Nigerian bees.
The other thing I suggest is to remove the link to that post from this site, it does lead to a fair bit of your own personnal details which I take it you dont care about so much as you deal with criminals every day anyway but still we do prefer our visitors to remain safe, the choice is yours
