> it's a bad idea to supply ANY personal information to random strangers How about your photos? Those are as PII as it gets. If you're not careful (and majority of people aren't), and upload the same photo you use for your linkedin or twitter account, a 5 second Google Image search can easily reveal your true identity. In fact, I have, in the past, emailed OKC and others and asked them to put measures in place so when a user uploads a photo, it's checked against various sources online and if it's a match, the user would be warned that it's potentially revealing their identity. I'm not sure if they took note of that.
