Georgia, they didn't verify signatures in Georgia.
"First, the audit does not include a review of signatures on absentee ballot
applications and ballot envelopes to confirm the validity of the statutory signature
verification process by the counties. Our analysis of your office's publicly
available data shows that the number of rejected absentee ballots in Georgia
plummeted from 3.5% in 2018 to 0.3% in 2020. This raises serious concerns as to

scrutiny of absentee ballots. In fact, it presents the issue of whether some counties
conducted any scrutiny at all. "
