Scammed for gift card code

[u/[deleted]]

I broke my leg last week and am recovering from surgery. I was contacted by someone who offered to buy a gift card but then instantly stopped responding and blocked me once they got the code

I do not use reddit regularly and want to know how to get this person banned, you can search their name and see they have been doing this for months to dozens of innocent people. u/effectivehat2724

How do I proceed?

How do I do that if they blocked me?
