Basically, the confirmation that Qrow is not Ruby's real father is as follows:


 * Years ago, a fan asked Monty (series creator) if Summer Rose was one of the many names Yang goes by, which Yang mentioned in the Yellow Trailer. He answered that Summer is Ruby's mother and that Ruby and Yang are half-sisters. (And no, there's no possibility that he meant "Yang is Summer's half-sister" because Yang is way too young for that to be true.
 * In all the years that RWBY has been a thing, the RWBY crew have never ever intentionally lied to us, not even once. Monty had zero reason to tell us that Ruby and Yang are half-sisters, but he did anyway. The RWBY crew makes a point not to lie to us. If the answer to a question would spoil something or ruin a plot twist, they say something like "Watch the show" or "We don't answer spoiler questions", something that writers of other series should do. The retort that "Sometimes writers lie to cover up plot twists!!" literally does not work in RWBY.
 * So... Ruby and Yang are half-sisters, and we have no reason to believe that was a lie and every reason to believe it's the truth.
 * Ruby's mother is confirmed to be Summer Rose.
 * Yang's mother is confirmed to be Raven Branwen.
 * Since they have two different mothers, they must share a father.
 * As Sentry pointed out, this means that, if Qrow is Ruby's father, he must also be Yang's father, which would mean he had sex with his twin sister to produce Yang. This is something the writers most likely will not do.
 * Plus, we see an obvious resemblance between Yang and Taiyang, so since he is Yang's father, he must also be Ruby's father.

Therefore, by following logic, the confirmation of "Ruby and Yang are half-sisters" is also confirmation of "Qrow is not Ruby's real father" by extension.
