If `they'
submitted their application about 6 months ago, like you said in your initial post about this issue, they are beyond the `1/4 processing' milestone.
Since IP addresses are logged when someone posts anything here, it's always possible that CIC
could ultimately contact you to find out who this couple is, so that they can investigate their relationship. This would obvioulsy require the assistance of the law firm that provides this website, but if they want the information, I'm sure they know how to get it.
Many here believe that CIC at least `peeks' into these forums occasionally.
