70 people polled out of a population of 4700 would have a 12% margin of error at a 95% confidence level, if it was a random sample. 500 people polled lowers that to about 4%.

If Blizzard were a lot bigger--say 100k people, a random poll of 70 would still be 12% and a random poll of 500 would still be 4%. You can play around with the numbers here [1].

The margin of error on a poll, if the population is large compared to the sample size, depends mostly only on the absolute sample size, not on how big a fraction of the population is sampled.

The flaws in this poll are how the sample was selected, not the size of the sample. It's not a random sample.

And here lies the problem. How do we know that those people were not ahem, "selected"?

Well they almost certainly weren't selected. But there might be latent correlational factors that cause HK views to correlate with blind-membership.

They would still need to be willing to answer the survey. I have ignored plenty of Blind polls/surveys in my time there.
