Somebody created dummy profiles of women, and then redirected the _men_ who were contacting the non-existent women to talk to each other, with a little supervision. He prevented meetings and scrambled phone numbers.
It doesn't _seem_ like this is the sort of thing that would work (on a human level, not on a technical level), but it reminds me a little of that cat instinct extinction thing (cats give up on eating the animals they catch long before they give up chasing, playing with and killing them). The drive exhibited by these men is a little astonishing.
