Well how much to you write? o.e I know I PERSONALLY dislike one-liners and I know that a good majority of people do as well so if that's your posting style it may do some good to try and write more. On the other hand if you push out like a paragraph or two I don't see why people would hate on you for that posting length xD
Well perhaps it's WHAT you're writing? Not enough description of surroundings or character feelings? Dunno what to tell ya! I don't do one-on-one's or I would totally RP with you just cuz I'm curious xD
