This email really freak me out

A machine-learning company named Qdrant recently sends me a promotional email (as attached on screenshot)

this, really freak me out!!!!!

- the email address that they're send are never being on the same account where my real name belongs

- the email address that they're send are never registered on my private github account (with m real name), I have 2 github account (company & private), both of them are unrelated

- they marketing data are based on my github stars? wth?

"Relation" of my data https://ibb.co/MRXnK3B

I come to ask directly to the person who sends me the email, and they're just replying with:

- what is your email?

- you are not into machine learning?

really no idea how they got my real & well-connected data, any suggestion to prevent this on future?
