eHarmony, where I met my spouse, used to be like this in the 2000s. $249 for 3 months of access, they chose the dates for you (after filling out an extensive, 1-hour questionnaire) and you could NOT search. It was a digital version of a very old school, professional matchmaker. I remember getting an average of 1 match per week (no date guaranteed from a match, it just afforded you the possibility of communication, both sides had to agree to it after reviewing the traditional writeup and pics).
