At tumblr I've stumbled upon a post which contents bothers me a lot and if it has any relation to reality it's 100% illegal (someone offers to have sex with his children).
I'm not a citizen of US and I don't know anything about the nationality of the author of the post - I'm mentioning this because my understanding is that tumblr obeys to US laws.
My question is - what set of actions I should take to make sure that this somehow end up as an registered and investigated crime? I mean I can reach tumblr support and report severe abuse however this doesn't guarantee this this will go further rather than just banning the author.
I mean have I encountered something like this offline I'd just call police.
