People who love flashing websites could not even participate. It looks like all the possible answers were for different levels of being annoyed.

I doubt there are many, but the result is probably skewed.

There's bias in pretty much every poll result, but I doubt the reason you provided has much of an effect.

People who truly "love" flashing elements (I don't believe they exist) will just choose "I barely notice these", and it wouldn't affect the conclusion.
