Then that friend is talking to another friend, who asks, "Hey has anyone met Dan Druff?", and FAB's friend replies, "No, I haven't, but my friend FABismonte went to Ruth's Chris with him in October."
That friend of FAB's friend then would know that I went to Ruth's Chris with FAB in October 2019, even if neither of us know the friend of the friend. So then the friend of the friend could show up on forums and attempt to scare me by saying, "I know you went to Ruth's Chris with FAB in October 2019, and you paid with a credit card", which would be a pretty easy guess, because most people pay with credit cards at steakhouses (especially if they're not associated with casinos).
(I didn't really go with FAB to a steakhouse, this was just a hypothetical.)
