Its a legitimate question. Luckily zero deltas were just one part of the Q proof. We had Trump saying things people asked Q to get him to say. We had uncanny future predictions, and we saw Q stringers in action. So we were sure that Q was legit regardless of the deltas, and if Q at that time trusted CMZ then we have no reason to suspect the deltas as well.

Even with the new Q - I am expecting other proofs beyond deltas. The proof is always in the pudding.
