Why do you think people feel so comfortable jumping into inboxes asking questions feeling entitled to responses?

I don't know but it can make me wonder about the site as a whole ,had two people inbox me after hearting a couple of my posts. I'll talk to pretty much anyone ,but after like 2 messages i get ,ok give me your email ,your phone number ,just so we can stay connected .When i responded i'm not comfortable with that ,blocked at least it saved me a block .But it's obvious they wanted something other than casual conversation.
