I received this as well and reported it to HiCal. Here's their response:
"That was from a member from kenya sending a PM to our other members, I have located & deleted them, you wont be getting any more Emails! Thanks, Dave."
So would appear that their server and our data is secure. Someone just created a user account to spam us with PM's. That's pretty tough to prevent.
Just got 2 emails from Alice this morning.
