I know that I can sign things on a brand new device without making an account. They can log what any web site can log. None of it really proves anything, except as other commenters pointed out - if I sign tons of stuff with the same browser/session, with an account I made, or if I used some premium ID verification they offer. (which I've never done)

My point that it doesn't really matter that much. If I DocuSigned some contract, delivered work described in the contract, maybe got paid for some of that, and then later some dispute comes up.. at that point we're arguing about terms or other facts.. Neither party is going to be in any position to argue "oh I never DocuSigned that agreement" because all of the other work and communication and transactions are enough to prove that's not true.
