Does 'tipping' increase the chance of finding a shiny?

Question

Is it confirmed? I am asking this because it's later in the year and we may now know.

Answer 1

From what I've seen, we have no way of knowing for sure unless someone from Nintendo decides to shed some light on the matter. Some people say yes, some say no. So its inconclusive for now.

Answer 2

NO.

No it doesn't, it's just a rumor.
We don't even know where that rumor came from and if it came from a reliable source.
All tipping OFFICIALLY does is, in Pokémon Y/X, increase your style level,
which by the way can be done in faster and more economic ways,
and award you with the medal "Gratitude" for generosity.
Here the source.
