I was a bit confused if I should post this here as I am new but I want to help.
Keldeo and Meloetta both are reporting what I am entirely sure are false positives.
Examples
http://www.pokecheck.org/?pk=3753707 <--- Keldeo has perfect IVs which is basically impossible for any poke even more so for an event.
http://www.pokecheck.org/?pk=3704309 <---- Perfect IVs and was met before the actual release date on March 4.
http://www.pokecheck.org/?pk=3762599 <-- Meloetta has 4 31's IVs and 2 30's
