What's a Pinning Attack?

There's a lot of sites to this discussion and I don't, we're definitely going to forget or miss something. But hopefully we'll get the most important ones at least during this episode. Why was this future included in this version of Pitman core? Well, what was the original argument? Because there was a pull request. And basically these protocols are being burdened by some of the details of the RBF rules. That was the argument.
