Gmail started putting my CB e-mails in the Spam folder about that time. I marked all these e-mails as "Not Spam" and gmail stopped misidentifying incoming CB e-mails as Spam from that point on.
Perhaps all CB models need to ask their Followers through their Twitter accounts, CB Rotating Notifier apps, at the top of their Bios in the "Real Name" section, and in a large flashing GIF image in their Bios, to check their e-mail Spam folders for CB e-mails and mark any found there as "Not Spam." If enough Followers do this, the e-mail Spam filters should create a universal unblocking of CB e-mails that applies to all recipients, not just in individual e-mail accounts. CB Admin could post prominent notices on their site too.
This could be costing models (and CB) a lot of money. I created an account to post this reply as soon as I saw the comment.
