People making those "looking for friends" posts... you guys end up meeting anyone?

I see a lot of people make posts here like "Hi, I'm 29F/24M/30M/etc. and I'm looking for new friends!"

I'm just curious, has anyone here made friends that way? How do you guys do it? Do you guys DM each other and end up meeting up? It feels like a very ineffective way of making friends but I could be wrong, but it seems like people want people to come to them rather than going to an activity or meetup with a set time and schedule.

I see a lot of people doing it here, so wondering if people have had any success with this tactic.
