> On the rest, if you believe that, then you must have been absent for the other million times when an individual was thrown into the garbage bin by Google, and told "you did something wrong (maybe), but we won't tell you what, nor will we ever respond to you again."

I've seen this a lot (too much). In fact this attitude of "Google sandboxed us and we have no clue why!" is as old as SEO forums. I've helped people fix their on-page and backlink issues. I've submitted successful reconsideration requests. I've made ads cheaper by linking them to higher quality pages. I did not fix this by picking them out of some hypothetical garbage bin. I fixed this by fixing their honest and dishonest mistakes and making them compliant with the quality guidelines.

Here at HN we have hellbanning. Do people get hellbanned by mistake (probably, but hopefully rare). Should we respond to every single person hellbanned, and explain to them what they did wrong, while they continue to be oblivious haters? It is a matter of how you view it I suppose.

I do not think that half-made-up fact is true, but I will not challenge you on this.
