So I've dabbled my way through tinder/bumble, and I've noticed a sort of trend, it's that if I don't reply to a guys message right away they seem to take it personally and then say something snarky and sarcastic -- name calling ie. bitch is another big one. And it's actually only guys who seem to do this. I've never received a massage like this from a woman. When someone stops talking to me I assume that maybe they are busy, out living life, or maybe they've lost interest. Not always ideal, but wouldn't hold it against someone, think ill, or send some like condescending/sarcastic message to them regarding the situation.
