WTF did you do that? Has somebody asked you?
Please unlist FindCoin from your exchange.
Once you release the source code people are free to do whatever they please with it. It's not an established exchange, it has little to no volume on all coins, it's not that big of a deal.
I agree on "low-volume exchange can't hurt", I disagree on "free to do whatever they please with it".
Yep, people are free to do anything - if it doesn't hurt other guys; if someone wants to dump FindCoins because he's in urgent need of money - he should consider selling it in unofficial trading thread first; but please don't spam all exchanges for listing FindCoins just so you can dump them at any price, and leave other guys/holders with cheap prices.
Living with solely egoistic behavioral model implies that everybody can treat you, or your interests as insignificant too - and it usually ends bad for the one who starts behaving like that, not the ones who reacts accordingly.
So, please, do what you like, but don't hurt the community - if you don't want the community to find you and hurt you
