what exactly is "white hat link building"?
There's no such thing IMO. But there's a huge variety of opinion on the subject. Some people would label guest posting as white hat for example, but there are loads of different types of guest posting (some of which is quite spammy and definitely more black hat).
Some people say black hat is just pure spam stuff like comment and forum spamming.
IMO, anything done to manipulate search rankings can be considered to be black hat in as much as Google is likely to take steps to counteract it and therefore it carries a risk. "White hat" is generally considered to be algo proof techniques.
Stuff that might fall into the low risk / algo proof category could be links you gather from press attention, link bait, viral marketing and so on.
Stuff that carries more risk may be directory submissions (SEO directories), forum spam, comment spam, article spinning, link exchanges, link wheels, etc.
