If you find above creepy, you should probably be creeped out by spam filters too (for at least 20 years now). Those are some third parties deciding what will get into your mailbox and what will not, based on questionable criteria.

There were several business opprotunities just this year that vanished just because email providers of people who inquired to me over e-mail blocked my responses with 5xx error. Those people just think I ignored them, but in reality it was their provider censoring e-mail. They're not in control of their e-mail so they will never know.

What's actually creepy here is that some unknown person is sending unsolicited messages about a group of people organizing to harm the receipient, and seemingly doing this en-masse for many users.
