It's a bit nonsensical that it should fall on a person to prove the negative (that they didn't sign something), as opposed to the party claiming that an action took place having to substantiate their own assertion. But I can believe this ended up being the precedent based on the "golden rule".
It seems like a pragmatic individual solution to address this would be to sign with an X or line or whatever, and diligently keep a log of everything you sign (perhaps facilitated with a phone app, with a conf code to write next to your signature). Then, when the supposed event isn't in your log, it should be back on the aggressor to prove their case.
