so my files aren't just selling, it has nothing to do with my decision of no more uploading there, are we talking about files with previous flags, over 100, etc?

I'm not sure that I follow exactly what you mean, but I'll try to answer:

Six of my last 20 sales were of files that had more than 100 sales, only one was of a file that hadn't sold before - and even that was an old one. Of about 40 files uploaded in May and early June, only one has sold and most of them do not have a single view. I didn't upload between early January and mid-May and then I stopped again when they brought in the "main collection", so I've only uploaded for about a month this year.
