Here is the article that was presented as evidence
here and is likely what lead to your ban.
Rather than posting imgur images of your PC, you could just edit the article on the original website to prove you really own that website and then drop the admin an email in the address provided with the new link.
Updating this thread with the info would also help.
But, in these cases, wouldn't it be better that if I publish an article elsewhere and republish it here, I add something like, "this article was originally published in xxx..." I'd say I've seen it sometime, not on this forum.
Otherwise, what the OP has done, if what he says is true, is not plagiarism, but it's not 100% honest either.
