Signatures are a lousy form of validation for voting in my opinion:

I'm a Washington state resident and because I sign a lot of checks I have two forms of my signature: My 'fancy' signature that has every letter of my name and my check signing signature that is a scrawl of simple squiggles.

I used my fancy signature for voter registration and accidentally used my squiggle signature for my fist mail in ballot and did't get any kickback. I've used it for six years and King County elections still has never questioned it.

As a counterpoint, I also live in Washington.

About five years ago I decided to change my signature. The first ballot I mailed in after changing my signature was rejected for having a non-matching signature, and I had to prove my identity and update my signature on file with the King County elections in order for my ballot to be counted.

My signature ended up changing over time and I had to update my signature with the county elections office in Washington to stop my ballots from being rejected. So really not sure how you're slipping by.
