Ok, guys, it might be too late but, well, I did my best
It's really early dirty beta and has some bugs in memory leaking on server side but it works somehow so pls try not to kill it
http://nc2chain.info/top100Just in case it could break at any time I saved a copy of the result here
http://pastebin.com/bZuyC3dSSo this richlist doesn't include addresses of excahnges?
I have over 707K of NC2 on Bter and it doesn't show here
Short answer - there is no filter
Long version:

You can post your deposit address on bter you send your coins to or you can investigate by yourself using searchbox (top right) on
http://nc2chain.info and looking at transactions and final balance.
I guess deposit addresses are transit only and your coins are mixed with everyone else's coins on that exchange in exchange's wallet.
And btw, I can see my local wallet address there and it's shows the right balance.

Can anyone else confirm is top100 working correctly for you or not?
