not that i care too much as it is your business and your decision to make - but i think that shutting it down is the worst possible scenario if you really want to accomplish what you said - this void will be filled sooner or latter by someone who will care much less about whiteknighting around - personally i would redirect part or whole income to charities etc. if it make me sleep better - that way bad people that use this or similar service will share some wealth (whether they like or not) with good people
