Update: My bad! I was displaying my email at my dev.to profile... Still it's good to know a scammer who is around, this happened just a few minutes ago...

I have a unique email through burnermail for most services I use, including dev.to.

Recently I got an email with body "hola" and an empty subject from a scammer and to my surprise it was towards my dev.to email address? How did they find it? I haven't used it anywhere else and I haven't published it anywhere.

Any ideas? Has this happened to you too?
