Single people, does sliding into DMs actually work?

I haven't been single in a while but I'm curious, does sliding into one's DM's actually work? I'd love to hear from both sides, people who shoot their shot and those who have received DMs that have led to something...more.

I feel like I've seen a lot of stories that have come out about famous people caught for DM'ing regular people trying to hook up and I've always been shocked because I had no idea that could work? Also, aren't there a lot of scammers out there? IDK!
