You really should go read this article on shame culture at First Things. We need to stop feeding the online Outrage Mob, and ruining people’s lives and careers (and sometimes endangering their lives) over things they say online. This has been out of control for a long time, turning private matters into public spectacles and taking sinful things said in public over the top beyond all sense of rational proportionality.
Before I go further, let me say this: Shame in and of itself is not a bad thing. We have come to think of shame as bad, so “(whatever) shaming” is seen as an immoral act. But if you do something shameful, you should be shamed for it. My pastor says that God gives us “pain to protect our bodies and shame to protect our souls.” When properly directed, shame points to our sin and leads us to the cross. Shame over our sin makes us realize how helpless we are before God and how we need the blood of His Son. Shame leads us to restrain our bad impulses and put more of a filter between our brain and our mouth and/or keyboard.
