There was a guy from Maine who messaged me a few years back on a similar pretext and became super intense and weird. the last straw was when he got arsey about me not replying to him for 15 minutes - when I was walking on icy pavements to go and get the train to visit my dying grandad. Imagine thinking that a random person on a gameshow owed you anything because you bombarded them with compliments!!
Have had guys be pleasant/a bit jokey instead of being like that tho, and a few times it’s been a totally platonic approach to express admiration/that I’ve inspired them (or for one guy, who had been on the show years before, it had inspired his wife.to apply for the show). But yeah more usually it’s a bit creepy.
