So... As a participant in Russian language and literature Olympiads (at the city level), I fully support the idea of promoting literacy :) Mistakes are too jarring to the eye, IMHO, but if a typo or misspelling was made intentionally, I think that's perfectly normal. However, I have many problems with commas, and accents always shift... But here, accents are not so important; correct spelling is more valuable.
P.S. Sorry for replying only now :o
