It may be against some rule, but when I come across one of those type of profiles (other than when I am trying to source something), I clean it up as best I can, getting rid of "* Add other sources here" and moving the gedcom reference to == Acknowledgements ==, then I put {{Unsourced}} at the top.
Without a tree to refer to either in FamilySource or Ancestry, I don't consider it sourced. It doesn't change anything for the counts if you are looking for sources.
I sometimes feel mean doing it, but I am consistent and I really believe they aren't sourced.
