There is a fine line between legitimate research and illegitimate harassment. In my view, simply looking up publicly available information on a person, including trying to tie disparate records together, is legitimate. In my view, the line is crossed when someone tries to tie an individuals online persona and real world persona together and publish those links for the purpose of harassing or intimidating that person. In my view the real issue is the harassment, intimidation, and implied threats, not merely the collection of the information itself.
