I think this is a fair policy, however I disagree about needing a "warning" in regards to intentional walks directly leading to a loss (as was the case that started the major debate on this).

I think if it is added to the rules that such behavior is not tolerated and is grounds for removal/penalty that is warning enough. My concern is that the "warning" part might allow a team one violation, or one series with multiple violations, to go unchecked - which could be a big deal at the end of the season where one loss could put a team into a lottery.

Its better to be strict and back off if needed than to be lenient and try to be harsher than expected.
