How did the client "made me delete some articles, not the whole website?" You said he accused you of deleting the website, and he had screenshots. It doesn't matter if it was one letter or numeral, you did not have a contract or written permission to touch his site.
In one sentence, you say you didn't delete anything, and he made you delete. You deleted the website, in part or whole, without a contract or permission. This problem is entirely of your making. No one can make you do work here. You decided to work without a contract or permission to delete content, and apparently, did not have the understanding of why you save a copy until the site is completed, and sometimes, even after?
I see no scam here, not from what you have posted. The client did nothing wrong, and you need to accept that before you lose everything. You broke the rules; the client did not break the rules. You merely had to follow the Terms of Service, (you agreed to abide by it) but you willingly decided to not follow the rules. Even worse, you are attempting to blame the client when you possibly damaged them by deleting the site. The problems came from you, and only you are to blame. If you deleted any part of the site, you could be liable for damages.
