A gentle reminder that if I don't know you, your choice of first contact with me (or, really, anyone) probably shouldn't be sarcasm or "playful" aggressiveness. Online communication often lacks nuance and context, and I will just assume you're a jerk and block you. Remember: The failure mode of 'clever' is 'asshole.'
This toot brought to you by more than one to-me-rather-obnoxious response here, followed by immediate blockage.
@scalzi Very true. It's a good policy not to tease anyone till you're SURE you're actually friends.
I don't remember everyone I've chatted with on social media. I could easily end up blocking someone for a jerkish "first contact," when we've spoken a few times and their name hasn't stuck.
I'd say teasing becomes appropriate when you've been chatting a while, and are actively seeking out each other's posts. Not after a casual chat or two, and not by way of hello.
