psychologically damaging harassment
This is vague and subjective on a case by case basis, which makes it impossible to "criminalize" objectivily.
and not a small degree of invasion of privacy.
Bingo. Invasion of privacy and exploitation (since it was posted on the interwebs)are the crimes committed here. The reasons and sexual preferences of the involved are not important. The suicide is a completely seperate incident and cannot be pinned on the bullier.
