Depending on the script (if it's configurable), you can send the request made to your own server instead of some analytics solution and redirect that request using a CNAME record. Combined with the script being served from you own domain, blockers will think it's a regular request and won't block it. They usually use a blacklist to filter unwanted traffic (like to GA). As we are still working on Pirsch, we don't have a documentation to explain the setup in more detail yet, but you should be able to find instructions somewhere.

[Edit] Okay, so it seems like blockers will catch that, see iamacyborgs comment. But we will provide a nice and simple backend integration which basically will do the same as the script, but is unblockable.

[Edit #2] Looks like it will only block cookies using this technique, so it should work as described.
