Over the past couple of months, we seem to be getting all these automatically generated shopping cart rules being created. They have the name of "Alert #691", "Alert #697" etc. The incrementation appears to be a bit random (but always increases). We get about 2-5 of these rules per day.
They appear to be giving a 5% discount, but none of these have ever been used by a customer.
I have no idea what would be causing this, does anyone else?
