after you've messaged for a few days and they ask for your bank details,you tell you've had problems with
your email being hacked and don't want to give your details out.you then say you can pay cash and have it transferred to them but you need their bank details ,to make it sound credible ask them to send it to one of your other emails (Which you say hasn't been hacked and is safe)and you will pay them in a few days.
a week later you send an email from the new email address saying this has been hacked too and it might be a good idea to change their bank as you believe hackers have their bank details.
Give it a few days and then block their email address from your emails
leaving some worried scammers behind
