This part is so~ me.
I know of people dropping posts in DMs shamelessly but, I just can't do it and when I have needed to, it is not natural at all.
I too, can't do it.
I can't help but imagine how angry I'll get if that's done to me. (Though while I don't check the links at all, I still try to talk some sense into them. So if they want attention they got it.)
