(I would like to mention that I'm not actually performing IP checks, I'm just requesting them via Special:Contact.)

At any rate, those accounts could be sockpuppets, but they aren't really disrupting the wiki enough for a CheckUser to be justified. However, given that you are the one running the tournament they are commenting on, I'd recommend just not counting their votes if you believe they are attempting to manipulate the results.
