Anon's preferred tool are the array of open HTTP proxies available. They provide relatively weak anonymity, but in scale it works well enough. LEAs have to subpoena the proxy owner and their ISP for logs, usually the owner has very poor logging anyway, often they're based in a foreign jurisdiction... There just aren't the resources available to go after them in any real numbers. They can (and do) go after a couple of people to make an example of them, but they always seem to pick on the low-hanging fruit who didn't go through a proxy.
