He actually gave you credit hence he mentioned your name. This is the internet dear, he can as well say he has never visited your blog. When he started posting your story, seems he warned us of a place where your story is being printed for sale and 3 websites where more than half of your stories are published with another title.
My advice is, make friends with him and ask him to give you the name and location of the printers and the address of the three websites instead of being his enemy. He can also help with publicity.
You know how I do things? I take a situation, look at the blessing instead of the problem in it and use it.
He has deleted almost all your stories on the page. Just throw-off and delete accusations from Nairaland and your blog and try to get him talk to you....... privately.
This is my one cent on the matter.
