I agree that, elitist as it sounds, estimating the reliability of reports at least partially based on who reported them makes a lot of sense. For a lot of the most frequently reported geysers, it would also be possible to do basic smoke checks for whether a time is reasonable, and automatically flag questionable reports for review. For example, two eruptions of Plume ten minutes apart, or a four-hour Riverside interval, or even a nine-hour double Riverside interval would be suspicious. So would Penta during or shortly after Sawmill (almost certainly a steam phase eruption). Infrequent geysers like Splendid, Morning, Giant or even North Goggles in recent years could be flagged automatically. Such analysis could also catch sudden changes in activity, like when Lion went overnight from have series of three eruptions or fewer to as many as 30 a couple of years ago.
