No one can check those articles because you haven't posted them anywhere. There is only a screenshot of folders in one of your posts. Why don't you upload them to Google Drive and set the visibility to public for anyone that has the links to them. After that, you could share the link in OP. Unfortunately, making them public can also result in your work being stolen, so you have to be aware of that.
If wwzsocki claims that your articles were of low quality, that's a subjective call, and that's his opinion. If he expected something better, you might want to discuss it with him to see what can be improved. Assuming, of course, that everything you said is true.
this is all BS what he said. don't believe it at all, that has nothing to do with the truth
case is simple I paid too much and he never sent it back
I will be happy to invite one of our DT to group where he worked for us and where we talked (where I am admin and he can't delete anything) and there you will see how we have spoken and what happened after his last article, that he removed himself from group and said at end "enjoy" to the last article - like a total scammer, because he promised to send it back
I don't think there is any other way to prove it, of course the payments, I have them all
To explain his story - is of course total BS, we worked on per article basis, soon I will provide his addy to DT1 member that will be able to check everything, that I paid him per article from start.
