Hah... The guys on the scox message board automated this pretty well; there was a user named warmcat who even opened sourced some of it.

The Reddit comments usually aren't long enough to be meaningful, and I think that there are now organised p&d teams, so that level of investigation isn't very useful anymore

You'd be surprised what you can get out of short Reddit comments if they're posting in multiple subs for long enough, see https://redditmetis.com/ for example.

The Yahoo comments usually weren't that long either. The key point was that while each individual post gave you, on average, only a little but of information, in the aggregate you got enough to narrow down who the source was to within 5 people. From there, you could usually narrow it down using "legwork" etc.

With something like Robinhood, where you're trading, presumably they have your bank details (and phone details) so pinning your trades on a irl person is a given.
