Alleluia!
Things are getting better.
The dates are as follows.
May 26th: 1,800 BTC loss for Poloniex because of the Clam crash.
June 6th: Poloniex covers its loss by seizing money from its customers.
June 14th: Poloniex has realized something went wrong, and it starts to reimburse its customers. I have about 10% back, and in an email, Poloniex wrote that "You can expect additional payments in the future."
It's great, great relief, even if I'm still waiting for the remaining 90%.
Having lived through a few "socialised losses" over the years, I remain somewhat sceptical. That initial ~10% could represent the easiest funds to recover from overdrawn accounts, or perhaps a portion of Poloniex's reserves/operating funds.
At least they seem to be repaying in BTC - like for like - rather than some internal token which has its value fixed to the exchange rate on the day of the event.
