Stop BBM from accessing my phone contacts

[iMore Question]

I didn't realize that giving BBM access to my iPhone contact list would result in BBM sending out an invite to all contacts. I assumed it wpould simply let me know who was on the BBM network and I could then decide who to invite as a BBM contact. How can I reverse permission so that my phone contacts aren't pestered by BBM?
