I keep going round in circles on reading an eharmony review—is the personality test actually accurate and I'd rather ask than guess. Same story on accurate mainstream apps: how honest the pricing page is matters more than the length of the feature list. The test mainstream apps angle is worse, because how much sits behind the paywall is the number worth watching, not the length of the feature list.
Test is where I'd start, since the platform resets your filters after an update, and it skews every review you will read. I judge accurate mainstream apps on one thing: the platform locks messaging behind a subscription, and how often the same faces reappear suffers for it.
With test, the honest advice is to run a reverse image search on suspiciously polished photos, based on a fairly small sample. Where reading an eharmony review—is the personality test actually accurate is concerned, the practical move is to test the search filters before uploading anything. Anyone who has tested test properly, please weigh in.
