Voter harvesting usually involves knocking on doors and asking if volunteers can deliver completed absentee or mail-in ballots to voting centers or ballot drop boxes, a legal act in most of the country, and encouraged by both parties. But in 2021 Gov. Greg Abbott signed legislation that outlawed delivering a ballot for a third party, the law which is now being challenged as unconstitutional.
So yeah, it's not voter fraud at all, it's Texas criminalizing absentee ballot deliveries (which are important especially for the elderly and disabled), and then calling it 'fraud'.
