I sincerely have no idea why someone puts bitcoin in that place after seeing that rule.
If a couple of pools were interested in fucking up MP's reputation, they could start taking longer to include transactions into blocks if bitbet addresses are involved. Just take care to not wait for way too many blocks, otherwise the pool's reputation get fucked.
Why do people who have no idea about anything (such as you) feel the need to prove it in writing? Go start a pool, fail, then see why the pools that succeed don't fuck with the Central Bank of Bitcoin.
