Sentence like this is wholly deserved for anyone publishing revenge porn. Her excuse was pathetic - unresolved trauma from her father having an affair 22 years ago? Come on, this was malice, pure and simple. Same as any man doing it to his ex.
As for those saying sentence is excessive in comparison for rape/sex offences, yes it is much higher but that is indicative of those sentences being unduly lenient not this one being excessive.
I do think an example has to be made on this sort of crime - it's just too easy for people to do it, even in a moment of temporary madness or upset. This woman also made a special effort to make it as humiliating as possible - she didn't just publish them but set up a communications directing callers to the OW's poor husband. I don't buy the suggestion she didn't know it was criminal to do this -I do think her sister may have thought she could help her avoid serious charges.
The dad who had the affair is a prick - clearly no censure for him - poor helpless guy passively seduced by home-wrecking man-eater??
The OW was as dumb as shit to give her lover intimate photos/allow him to take them. I simply do not understand people putting themselves in the position where they could be blackmailed or humiliated by this. At the end of the day even if you are in a rock solid relationship there is a risk with these pics, you don't know what may happen, things could go sour or they could be viewed accidentally. She still doesn't deserve this treatment, no-one does, definitely not her husband.
