Unsolicited Checks in the Mail for Tax Certificate

[Alex T.]

I have been getting checks worth penniies from a person I do not know. The memo line reads the street name and "buy tax lien" along with his email address. I don't intend to reply to this person nor cash in the coins. Has anyone else received unsolicited checks prior to any communication, and how did you respond? This feels like some kinda trap lol.
