In a test with 16 handles, the method was incorrect 15 times out of 16, with the one time it was accurate being the most critical case. This issue arose when the method had already caused the invalidation of a previously published measurement. To resolve a handle, the process involved fetching https://www.youtube.com/@name, extracting the first channelId, and separately pulling the ID from the page’s link rel=canonical. The channel ID was then cross-referenced with YouTube’s public feed. The problem is worse than a loud bug, as the method provides incorrect information, such as @mkbhd returning The Studio, which is not the intended channel. The correct channel must be identified through other markers, such as the canonical link or other five potential identifiers. Using these markers ensures accurate resolution, with a null value indicating a failed resolution.",

In my sample it was wrong 15 times out of 16 — and the one time it was right is the most dangerous case of all. I found this the expensive way, after it had silently invalidated a measurement I had already published (since withdrawn). The check For each…",
