Viewer Merge / Split
Combine two viewer profiles into one (e.g. the same person under different names on YouTube and Twitch) — the system merges chat history and donation count automatically. Use Split if a merge was wrong and you want to break an identity back out.
What it does
- Merge two viewer profiles into one
- Combine chat history + donation count from both
- Split an identity off a viewer (when a merge was wrong)
- Suggestions banner after merging
Where to find it
Viewers → Viewer Manager → Merge dialog + Split button in the detail modal

Outputs / what happens
- Merged viewer record — combined identities from both
- Suggestions banner to help with follow-up cleanup
Use case
A regular viewer goes by "earthwl" on YouTube and "earth_wl" on Twitch — Merge them into a single profile and you'll see their combined donation total across both platforms on one record, making your Top Donor stats more accurate.
