Groveling is the perception that some of the people (including me) have when deciding what to do when they get shadow-banned. So I just end up dropping the old account and any reputation it may have gained over its lifetime to start over.
I understand that it's dramatic, but from the outside it feels like a process of begging for forgiveness for committing some infraction you don't even understand. To rub salt in the wound, we aren't even given the dignity of knowing when we have uttered words that violate the secret book of acceptable comments. We just have to infer after a sudden decline in comment engagement that we have been shadow-banned. This is infuriating to say the least. For a site to have a sanctioned method of giving regular users a permanent punishment which causes them to pour effort into providing comments that land muted is repulsive to me.
I apologize for ranting, but I have yet to see a strong logically sound defense of this practice. It's one of the worst 'fuck-you' features I've seen a site implement towards its users that make critical comments. Critical discourse is what makes this site great! Unaccountable shadow-bans chill critical discourse regardless of their intent.
I beg you to reconsider the practice in its current form. As I mentioned elsewhere, someone intentionally trolling will verify that they aren't shadow-banned anyway. The people shadow-banning hurts the worst are the ones who don't expect to be shadow-banned (i.e. genuine commenters).
