Add this in oscam.server

Code:
blockemm-u = 1
blockemm-s = 1
blockemm-g = 1
blockemm-unknown = 1
With this config you block all EMM's! This is useful with Sky Italia cards and other providers that send killer EMM's.

If you want to block global and unknown EMM's (they can flood your card and it is recommended to block them) and still allow unique and shared EMM's use this:

Code:
blockemm-u = 0
blockemm-s = 0
blockemm-g = 1
blockemm-unknown = 1
