"Blocked Role" versus "Member Role"

Hi guys -
Using BP Daily and love it ...
So, here's the deal - I'm trying to figure out he "default role" needed for new users that I want to be active on Buddy press?

I have the "member" and "blocked" options that seem to work.

The "member" option seems okay, but gives too many views of widgets (stats, etc) installed to the user if they navigate to the admin panel

The "blocked" option does much less of that while seems to still give the user ability to edit their BP profile, avatar, etc.

Any idea on what I gain/get with either one?

These users don't need to do anything except contribute through collaborating/commenting/viewing etc...

Your help is appreciated!
