I've moved plenty and you don't see me ever casually suggesting it to a stranger on the internet. Not once.
There is no one, no one ALIVE, who doesn't know about moving. Likely the person you suggested it to moved 5 times already and knows more about it than you. It's very possible.
Eat shit with your shit advice.
The person was asking about dating and you told them to move without knowing a damn thing about their life or preferences. It's really dumb.
