(Well, hello there! I haven't seen you around in ages man, how you been yourself? ^_^ I've been doing alright. Got into the RP community here a few months back, so I've been busy writing stories along with making new lolz. :D)
Just try be original and clever, like you did the first time. Also, don't have high hopes for weekend posts, as they tend to get buried. If you REALLY want to have a chance at being seen, wait until Monday to submit.
I have theories. For the Rarity, I reckon some people must have misconstrued that as erotic or covering up "nudey bits." As for the "football" one, a lot of people here aren't American (I'm not either) and had no clue what you were talking about.
