I found the issue: this thread is inconsistent:
It’s entitled “Petition To Actually Get Appluadible To Exist”.
Ryan said that someone had bought “Appaudible.com”.
Josiah said that someone had bought “applaudible.com”.
Until there is some consistency, I would also like to point out that “applaudable.com” seems to be available for sale. Not as much of a pun, but possibly a more desirable address in general.
