[WARNING] Poloniex BTS Hot Wallet is empty; Do they have the keys to their cold storage?

As you can see on Cryptofresh, the Bitshares account "poloniexwallet" is low on funds:

There's 103 BTS left in this account. Their cold storage account "poloniexcoldstorage" has 290 million BTS though; however those funds have not moved for over 10 months:

edit: the 103 BTS just dropped down to 8 BTS

Why aren't they filling their hot wallet? Are they trying to make bitshares look unstable to suppress the price, as it is a competing technology to their business model? Have they possibly lost access to their cold storage keys? If the keys are lost, what will happen to the price of BTS? What do you think?

I think that if they can no longer access 290 MM BTS, that will drastically reduce the effective supply, which could have a good effect on the price long term. In the short term, the uncertainty for BTS holders on the Poloniex site may cause the price to tank on that exchange specifically.

edit: please retweet this message to Poloniex asking them to prove they are not operating a fractional reserve:
