In their dating persona test (http://www.okcupid.com/the-dating-persona-test) there is the line "If you have any STDs please go HERE." wherein HERE was a link to match.com. It now goes to mingle2.com.
That link actually rotates randomly between their major competitors. In a few reloads, I got Plenty of Fish, True, eHarmony, and Mingle2. It's likely that they've pulled Match from that rotation, though.
To be honest, I wouldn't mind seeing that line disappear altogether, as it always struck me as being in somewhat poor taste.
