But mashing reload is what users are supposed to do by design of the web. That is, errors in internetworked systems can happen at a level high enough that machines can't decide if it is sane to retry or not, they should simply bubble the error all the way back to the user and let her press F5 if she wants to. Modern UIs might hide this, but users well know the web is flaky and understand it in their bones. So when they press reload they are sending important information.
