I'm not quite sure what you're asking. You don't upload any DNA data from AncestryDNA, or any other testing site, to Wikitree. All you do is list your ancestry name, or Gedmatch ID, or FTDNA info, on your profile.
I have been on ancestry and have a tree there as well as testing DNA. One site has nothing to do with the other, and no one cancels your account because you post about having your DNA tested.
If you are wanting to collaborate on your tree, then enter your information here on Wikitree until you connect to an existing profile (or multiple profiles). Feel free, on your personal profile page on Wikitree, to provide a link to your ancestry.com tree if you'd like.
