Sorry, you are misinformed or didn't remember things correct.
MOON never was listed at Poloniex, and never was removed from Cryptsy,
when Cryptsy stopped withdrawals and trading, MOON was present at Cryptsy with good trading volume,
that's why a lot of people in this thread reported their Mooncoins left forever at Cryptsy.
It's true that an original dev mentioned health issues before his sudden disappearing.

You're right, it's been a long ass time.
Mooncoin was however completely dead on cryptsy and was listed on the other largest altcoin exchange at the time, I just can't remember what it was. Poloniex wasn't that big at the time, but that huge exchange it was on, which also had tons of volume, got hacked as well and shut down. I lost a ton there. All my damn alt coins
