No, we aren't data mining or anything like that. This year the site owner, Bill J, switched the host site from Eve to Hoop.la. For whatever reason, the default profile settings is for everyone to get notified by email whenever there is a new survey posted or if anyone responds or completes it. Bill is going to look into how this can be changed.
In the meantime, please change your notification settings.
I do realize it is a big pain, and apologize.
