Assuming it's not outright foul play, it's prob more likely that the matching services intentionally boost your profile gets better reach/impressions as that's a +EV play, and reduce your profile reach when you're subscribed long-term.
To carry this thought exercise more, someone structuring this system could also treat hot/responsive/engaged profiles as an asset of retention and intentionally matchmake the results to optimize for a system to be engaged (vs to matchmake two people who find love and unsubscribe after).
