I have Firstname.Lastname@gmail but I never get any mistaken mail there.
Now text messages on the other hand... I get all sorts, at one point I was getting some for a Black Gun group. Now I am getting them from the DNC but they are address to the wrong name.
The scarier thing is two factor authorization text messages, I remember getting some for Facebook and Instagram. I never did anything with them but if not set up right I suppose I could get into someone else's account.
One time I got a wrong number and over the next few days coached a lady who was calling her friend for advice on her upcoming job interview, as she wasnt sure she wanted to make that career change.
I did the best I could to advise on the matter (sincerely) - but I never got a reply on the matter.
I always delete the message immediately after so the thread isnt there so I have no way of initiating a connection.
I still get updates in my email from this family and even had bank statement updates sent to me. and birthday wishes mean for the other sstave...
I have told them multiple times - but I am still on their family tree - for a DECADE
