*** Forbidden. Contains contacts. Message seems to be spam. ***

Hi there,

users on my website are complaining that they cannot complete a registration form and are getting the following message

*** Forbidden. Contains contacts. Message seems to be spam. ***

I tried adding the page to the Exclusions field but that did not make any difference. I would rather not exclude this page from the spam check so would appreciate some help to get it to work.

Regards, Mark
