Rant is about a doujinshi author/artist who has been posting teaser panels on dA for a something she's been planning to release eventually since '06.
Y'know, just because you acknowledge both of a fandom's top two pairings as reasonable doesn't mean you actually have to write both in the same story even if they overlap. Personally, my SportaRobbie is always set when Stephanie is still a child, while my most recent SportaSteph paired Robbie off with Pixel first, and the other didn't even mention him. I don't really care how beautiful your drawings are, pick one and stick with it, or if the SportaRobbie is really only one-sided like I suspect stop posting panels of Robbie fantasising and being so bloody coy about their context.
Giving misleading pairing information is already seen as a considerable breach of fannish etiquette in an online context where the reader can just back button and all they've lost is time and bandwidth. For something you plan to charge for, I think it might verge on fraud. Not legally, since I don't think the law would regard pairing as a major feature of a piece of fiction, but since the fannish community generally does, I think it does in spirit.
