Youre right that there are social rules saying you shouldn’t. But when you’re confident and have social skills you can break the rules.
If you trust yourself to have the social intelligence to pickup on signs of disinterest or irritation then go for it. Start with a casual chat and have 0 expectations. You’ll feel if its right to ask for their number.
If you know you dont have good social skills then just play it safe and find some mixed groups and just try make friends with as many people as possible.
The bots post better comments than most of their users.
