I'm responsible for my own OpSec, but we both know that public registries have their own vulnerabilities. Again, I think I detect a misattribution of responsibility. Nevertheless that was a single example, not the entirety of the means by which personal information can be gleaned by the unscrupulous.
My counter-position is that it is essential for we who have influence over systems design and policy to avoid unintended negative social consequences in the services we build.
It's akin to celebs complaining about gun control, stating they hate guns and would never have one themselves, as they are guarded by several armed body guards.
People want to be anonymous, but don't want just anyone to be able to send them messages. Okay, so who can send you messages? Who can post things you can see? What is your solution to this?
I believe it is most certainly victim blaming. The existence of terrible people may well induce one to recommend countermeasures, but the phrasing "stupid enough to put their personal details out there" is first-class (and thoroughly obnoxious) assignment of responsibility for bad behaviour to the victim of that behaviour. It's the same logical construction as blaming rape victims for their clothing.
As for "attract enough attention", the bar for that has been lowered in recent times to "one tweet".
These are not happy times to be a private citizen communicating online in anything but the most closed fora.
