The situation with high quality search results becoming inaccessible reminds me of what happened with expertsexchange back in the day. EE adopted a pay wall and in doing so sequestered a bunch of useful technical answers. Their greed turned against them and opened the way for StackOverflow to really take off and gain dominance.

I had over the years posted thousands of answers to question to Python, C#, AngularJS, Angular and React questions. I wiped all of them with shreddit the last couple of days. To give you an idea I have been running it for 2 days over seperate accounts and its still not done.
