Answer 1

This is possible.

Bulbapedia states that this is -----; which is a glitch Pokemon, AKA the invisible shiny bulbasaur glitch. The glitch is caused by AR codes like the Decamarks and encountered the exact same way (not the way he stated it).

Answer 2

Man, I start Pokemon rumours all the time. take it from me, this one is straight up whack. never happened to me or anyone else I knew.
if it did happen and you tried to catch it, it would more likely jam your game than let it happen. someone with a pc is just yankin' ya.
and if it is an AR glitch then that still means nothing, as it couldn't happen without AR and you have to willingly input a code to essentially mess with your own file.
