I need to write a blog post about the time an ad network told me that their required integration was to integrate their JS bundle that would send all text input to their servers. When I told them No Fucking Way (in not that many more words), they said they would need to get executive sign-off on a "custom" integration. The "custom" bit being us doing everything ourselves server-side and sending them a single opaque identifier for conversions.
