Twitter and some other reich-wing places were doing fucky stuff like promoting register-to-vote sites that didn't necessarily actually register you to vote. This is particularly true in Texas, because all the sites were online but Texas required you to register either in person or by snail mail. But the sites would display success messages and shit anyway.
There was also trump handing out hundred dollar bills and musk offering money to people to register to vote, both of which also seem to be against the law. Fuck if I know why the government doesn't seem to take this shit seriously.
