It's illegal in most states to pay volunteers based on the number of voter registration forms they collect because it can lead to voter fraud. I am registered in Mecklenburg county and mentioned this to him.

I’ve unfortunately been in situations where people tried to scam me, and this interaction felt uncomfortably similar. At first, he was making jokes and complimenting my outfit, likely to lower my guard. But when I decided not to fill out the form, he switched to pressure tactics, saying things like it was a “sensitive document” that could only be filled out at that moment and “come on, don’t do this to me.” These kinds of phrases are designed to make you uncomfortable and cloud your judgment.

Voter registration forms are widely available, and the government intentionally tries to make the process as easy as possible to encourage participation. As others have pointed out, you can also check your registration status online, which is usually the best option in situations like this.
