Server-side log-analysis solutions are not possible to block. I assume that piwik is running client-side javascript? Then it's in the interest of the client to block it; it's not a server-side solution anymore. Of course with self-hosted js, that's a cat-and-mouse game that the clients can't win anyway, but in the short-term the mouse has won.
