support@bitfinex.com regarding the "other things". I have mailed regarding the $10k 0.000000000000001 BTC bid that causes the P/L to be displayed incorrectly.
It may, sadly, take some hours before this is resolved: R is on France time. Nothing inherently wrong with being french, but it's four in the morning there.
The micro order is not the issue. The issue is that people's balances are wrong. Some report 10x unrealized swap, some report 2x-5x on their unrealized P/L, some report negative tradeable balances. Still others report that limit orders are matched but don't update their postions (but DO update their tradeable balance). PLUS margin ratios are fluctuating.
If people get margin called because of bogus data, it will be a disastrous nightmare trying to unwind all the transactions. ...and this is assuming Bitfinex hasn't been compromised and someone isn't doing all this on purpose.
WAKE UP RAFAEL! Most of those problems are DUE to the micro order.
