Apologies if this has been raised before

I had my DNA test done to help (hopefully) solve some of the roads that research and paper trails couldn't solve.
But has anyone else found it incredibly frustrating when a potential DNA relationship has been flagged up but the person hasn't supplied a Family Tree?
Yes, the website suggests you invite them but to do so, and some have Trees that are private (fair enough. At least they have one and can share information should they chose to) but surely most people would upload a tree if they were actually looking for a match?
I'm unsure why these people have paid for a Ancestral DNA test with no apparent desire to discover their ancestry?
I understand some might be working on theirs and with time one will appear I suspect some never post one
