OP is not saying that Google’s scrape still retains his reddit comments. He’s not referring to seeing this information on Google, but on Reddit.

He’s saying that reddit is retaining his comments and still serving those comments up when refreshed directly. They’re de-linked from his reddit account so he doesn’t see them through his reddit account, but the information is restored throughout the reddit site to be viewed.

I feel like I haven’t seen enough of that happening in the past though. Can you share some examples of where you’d seen it? Maybe Steam? No Man’s Sky?

What other apps debuted early to a poor public reception that got people to come back and try it again and successfully change their minds?
