Is it possible for a pool to discern you're witholding winning hashes and block your hashing power specifically from a pool?
If you divide your attack hash power among 1000 accounts, then the probability that any one of those accounts would find a block in a given a given year is effectively 0. No way to distinguish "unlucky" from "withholding" without a large enough sample size. Keep the accounts small enough and you will be indictable. (Sybil Attack)

Step 4) Don't submit winning hashes, reducing the REVENUE of competitors by 3%
When mining you don't know if you have the winning hash until after you submit it (sometimes not even then).
