I'm not sure of that extreme of a ratio, but many of my single women friends will use the app, match with people, and it turns out that loads of the guys are just really useless... so it's not clear whether the matches are actually worthwhile. Imagine a guy with a very interesting profile, who swipes right all the time. People match with him cuz he has the nice profile. Turns out that he sticks around on the platform for a long time. Suddenly this one person is responsible for loads of matches. So if you have these long-term users, they can generate disproportionate amount of matches with themselves, biasing the pool. This could be even more accentuated by Tinder-style algos. Somebody's popular? Of course their profile will show up more often! If you combine this with people on the other side matching pretty conservatively... then suddenly you can have a handful of men receiving the large majority of the focus. Paraphrasing some tweet, at least at parties the most popular guy can only talk to so many people at once!
