There was a service called Baller Alert (the name seems to be ungooglable now) that would stalk basketball players and send announcements whenever they were spotted in clubs/bars just so the women could try to flirt with them. https://duckduckgo.com/?t=ffab&q=baller+alert+30+for+30+brok...
seems similar to the big millionaire/billionare trackers in China that are big with the "find me a rich husband" crowd
