Why has my OSF profile been deleted several times? Why do all of my OSF preprints disappear several times? [closed]

I had two OSF profiles:

1. https://doi.org/10.17605/OSF.IO/T7PHG
2. https://osf.io/byn9p/

But they didn't work several times for a long time.

I wrote several e-mails to support@osf.io several times, but nobody replied me.

Why is my OSF profile deleted? Why do all of my preprints listed at https://qifeng618.wordpress.com/2020/04/12/some-electronic-preprints-posted-by-dr-prof-feng-qi-on-the-open-science-framework/ disappear from OSF?
