Could we just get their Bitcoin addresses (like PM trolls telling them you will donate), and then DDOS the hell out of them?? Then they will never receive money with the same wallet ever again, and hopefully leave here as well.
you're talk about serious criminal offense.
It is a global network, there is no way to know if they are US based from their wallet address.
its not SO global network. not yet. even not 100x from required size/flow. feds still can use data mining forensinc[statistica/activity analysis, mostly], for notable cost
let alone activity status relevance to investigation initiation/success.
point is, you never endager someone life, if he just make minor mistake, probably unintentional, right ?
same with IT warfare - responding violently for bitching is almost same as hurting kids.
of course, if trolls, does measurable damage, including society and/or health/lifes, its completely different business.
