The last email I got from them stated this:
I checked Helium to see if my article will show up, because I've edited some of them to sell here and wanted to make sure I can sell the full rights. From Helium itself, my articles don't turn up using Search. It does appear on Google though (with my Helium name "Carmela Almonte"), but the page no longer exists. Apparently, my bio page still exists but they've deleted all my articles.Because you cannot access Helium, or will soon be blocked from access, we feel it is only fair to remove your content from the site. Full rights to the work revert to you.
My question is will there be issues when I submit those articles here and try to sell the full rights?
