I had $200 scammed by a supposed bit chain website. The telemarketer that called me knew about this and said they could reclaim my money for me. The only way they could have known is if they were part of the same group that scammed me in the first place. I kindly asked them to remove me from their caller list and when they called back anyways I swore at them and then they repeatedly called me for the next half an hour until I blew an air horn into the phone.
