Close instead of ghosting, ladies and gentlemen.
This is supposed to be a serious sub looking for (generally) long term partnerships.
It doesn't take much, but if you're into texting someone here for days and the other party is putting in reasonable efforts to start conversations, it's just good manners to inform them of any mismatch before you move onto a better prospect.
Not saying each of the hundreds of DMs need to be responded to, but I'm assuming if it's humanly possible for someone to accept a certain number of DMs, it's also possible to close the mismatched ones with a cordial goodbye. Who knows, they can help you get hitched to your forever ever after. :)
Not everyone is dealing with high volume parallel conversations, and the participants expect this subreddit to be better than the dating ones.
Speaking as someone who has active conversations, ones that were ended gracefully from me or the other person (which felt so good), and also ghosted/blocked (which just solidifies the case against you as a scammer, unless the other party deserved it for being any kind of jerk)
