I am experimenting with Tinder subscription at the moment, and it feels incredibly exploitative. When you make a profile, matches are frequent and you can tell that you show up for people. However it gradually falls down with time, and the only predictable and obvious way to get back up is to pay for Boosts and/or Priority Likes.
Right now my 6-month old profile gets ZERO likes outside of the time it's Boosted ($3 a pop or something). I get plenty once I'm boosted, so the profile attractiveness doesn't seem to be a factor.
It feels like the app's algorithms are rigged to gradually push you towards paid subscription options. There must be a huge invisible market of Tinder whales given how exploitative it is, gambling addiction, loneliness, and desperation for dates are correlated traits and I would absolutely bet on Tinder exploiting this heavily.
