On Sept 1st, Bittrex delisted Boolberry despite have over 300BTC in volume and reversal to uptrend. They refused to engage in any civil discussion about the delisting. When I joined their support channel and inquired about it, they kicked me out of the support channel and posted their delisting guidelines on our thread via a sockputppet account.
https://bitcointalksearch.org/topic/m.21121918What's odd is 1 week before the delisting the market on Bittrex crashed from 15k Satoshi down to 3000 Sat then immediately recovered. Over the next week the downtrend reversed and went to breakout through 20k. As soon as buys broke through it triggered a delisting noticed in a similar fashion to a limit sell. I couldn't understand why anyone would dump all the way down to 3k Sat but when the delisting noticed came around it started to make sense it was Bittrex or an insider there dumping their holdings.
Even more odd, another Cryptonote project AEON has had its wallet in maintenance mode since May and is still listed there.
I thought it was interesting that they are delisting BBR, but not delisting AEON, even though AEON wallet has been in maintenance mode for going on three months now and from intermittent checking it seemed like volume wasn't that dissimilar.
Full disclosure: I don't hold any boolberry anymore, and do have some aeons.
My conclusion follows Occam's razor, the simplest answer is usually the correct one: Bittrex is engaging market manipulation. If it can be proved they are selling their holdings before delisting announcement it would be grounds for legal action since they knowingly took advantage of investors buy support to liquidate their holdings.
My suggestion is that someone start a class action lawsuit against them and Poloniex for unjustified market manipulation to seek damages for investors caused by their actions. The same thing would happen if NASDAQ or some other entity dumped their holdings before delisting an asset. If they want to impose KYC/AML policies like a real broker for traders then they should be forced to provide the same transparency to investors and delisting.

They don't seem to care for the communities who got them where they are at today and therefore we as a community should refuse to give them our business.
