eBird protocol for most introduced species (with a handful of exceptions) is for reviewers to invalidate the record with the flag "introduced/exotic". This removes the records from all public output, including maps, but they are still present in the dataset and visible on the individual checklists. I've heard that the rationale for this protocol is to reduce the clutter of introduced species on bar charts, although that seems pretty trivial and I'd like to see introduced species included in public output.
If anyone is interested in analyzing records of a specific introduced species, it's relatively easy to get these invalidated records in the eBird Basic Dataset download.
