If someone puts information in a public post on the web, thereby making it public knowledge, I will share it; if they don't, I won't. If anyone tries to out anyone in the comments here, their comment will be deleted; I take privacy very seriously. Social Justice Warriors delight in outing their opponents—see the outings of Zathlazip and Igor Sanchez—but I believe people who make some effort to keep Google from linking their identities should be respected, no matter what I think of their beliefs.
When I know someone's identity and I'm not sure whether it's public knowledge, I do a Google Advanced Search using "all these words" to see if any of the hits are posts made by that person. But if I make a mistake, please correct me, and I'll delete the name from my blog immediately.
