It would make a good competition. How many things can you find wrong with this logo...
Possibly the two worst individual howlers are the red white and cyan/blue? slash, I presume it's meant to be the russian colours, but the designer seems to have forgotten that white doesn't show up too well on a white background and made it a very light shade of grey instead. Also the words 'world championship' appear to be gratuitously and randomly coloured blue or black.
