I would suggest that this is not the right way to go about it and would like all to consider TomGullen's advice from this thread instead.

Problems:

- "doxing" is a bad practice from 4chan; it could reflect badly on this community and the organization behind it if some high profile case of doxing would come from YCombinator's forum.

- how much do you really know about the whole thing? You've heard one side of the story so far.

- It seems to me that people have no business "serving justice" or feeling "Dredd" from the safety of their computers in general. Standard legal measure have not been exhausted, and I'd rather suffer the occasional smalltime criminal than see civil society damaged by witchhunts.

Would you agree going through legal channels will be way more effective/possible if the problem maker's name/address are known?

I assume finding name and address are trivial in this situation once you go the legal route. Helping the OP with some information privately is of course helpful.

thanks for your effort, but trust me he's not worth it :)

Not sure why you were downvoted, I agree that hunting this person down is probably pointless.

but something should be done, otherwise he will continue to do it without being punished.. :(
