One thing for sure, usually, when you are in the cc loop of an email, it means that most probably, the email contents are linked to you in one way or another.
One thing for sure, usually, when you are not in the cc loop of an email, but suddenly you are in it, it means that most probably, you have been dragged in.

Something to hide?
There are many things, called ‘knowledge’, around.
There are also many things, which are categorized accordingly.
1) Must know.
2) Need to know.
3) Good to know.
4) Can don’t know.
If you are in the cc loop, most probably the category is around 2 to 3 most of the time.
