new customer email address contains my store name

I had a new customer place an email the other day, and it’s only today I’ve noticed that their email address is my store name @heptadecagon.one

Googling the email address and the domain yields nothing, my store hasn’t flagged the order as fraudulent, but I’m understandably suspicious. Has anyone had this happen to them?

Mystery solved! The customer uses disposable email addresses and uses store names to help them track purchases and spam.
