>I don't find anything wrong with a teenage girl being teased about a photo she posted to the internet.
Well that's telling.

Perhaps we have a different understanding what it means to tease someone. For me it means (and the free dictionary seems to agree) to annoy, make fun of, mock playfully without degrading the person.
More to the point, you are misunderstanding the stage at which the girl is victimized; when she is ridiculed. You are definitively blaming the victim if you think it's her fault that people other than her traded the photo around for whatever purpose leads to the teasing.
Kids kill themselves over this stuff, it's not so simple as, "deal with the consequences."
But of course it's easier to blame 'those paedophiles on the internet' than 'my little innocent boy'
