Could Reddit's "no personal information" rule be detrimental to some social justice causes?

Namely, the ability to expose people who say offensive things in real life. If you post a screenshot of what someone on Facebook said, you have to block out their names and most likely their faces too on this site. I think that's too bad, I'd love it if there was an SRS where we could share their personal info as well. I thought it was awesome when that bitch who worked for OKCupid got fired over some racist comment on Twitter.
