I had a car up for sale and got a scam email yesterday - noticed myself, so ignored it but today got a Scam warning email from PH - absolutely excellent feature, well done guys, but unfortunately I'm now getting multiple copies of the scam warning email....
That possible means the scammer tried to contact you multiple times, so it is sending the warning once for each attempt he made, despite the fact we will have blocked some of the messages.
If it doesn't stop soon then let me know and I will look into it.
