I think it just depends on your default notification settings, so ping is actually useful. If I want to bring you in someone's post, then you need a ping (unless you subscribed that person's page). But in your post or mine post I am pretty sure ping is useless as we both get notifications.
Honestly questionable, ya know... I don't go to people's discords anymore. They're just wasting time. Lots of horny kids? Retardness? Stupid emojis? Are we reaching stupidity? That's why I abandon Discord form time to time.
ACCA 13 is good too if you like culture. If you read ''About death''. then your best action would be reading comment section as well, there is a lot of symbolism... I didn't get it much without comments.
