EDIT: Had asked about Jeremy's complaint; see sama's comment below
RE naming names, the complain is public anyway, but still it's not something I feel great about. However, behavior like this is becoming more common (I spend far more time dealing with related issues than I'd like) and it needs to stop.
If you find a good solution to reduce the rate of this happening, please share! It is a huge problem and a major barrier to why many businesses are never started or die a premature death. People are inherently unstable and difficult.
Which makes being so public about this particular dispute pointless and ultimately damaging to YC's reputation. This post was a mistake and it won't help anything.
