https://etherscan.io/address/0x32be343b94f860124dc4fee278fdcbd38c102d88No, these guys are not insolvent.
They're being shamefully unprofessional in following up with their recent announcements about the BTC hardfork and BCC/BCH sidechain tokens that are rightfully the customers' who hold BTC on the exchange; as well as utterly disgraceful in handling their support requests.
I, for one, am not worried. A little digging and the dox for the CEO/Founder of Poloniex are on this forum. And anyone that's been in the crypto game for long enough has seen the same as I have; scammers getting eviscerated and devoured by this community.
Lol I think that everyone that works for Poloniex knows it is in their best interest to get their shit together and start telling us what's going on, STAT.
that BTC address is now empty.. lets hope they're just moving funds for safety before moving BCH to separate wallets..

edit: looks like this is probably the case since they appear to be sending withdraws from an address that received coins from the above BTC address
the ETH wallet has been inactive for 7 hours. edit: they just started moving funds again
maybe they're not insolvent, but something is up.. lot of red flags:
- support tickets unanswered for months
- withdrawals 'pending approval', not processing
- lots of wallets have gone down recently when there was nothing wrong with the wallet in question
- TOS changed 8/1
