i think most of these errors come from hearing things spoken but never reading them. so basically people who are poorly read suffer from these problems. a big one i see here on gaf is yay or nay instad of yea or nay. yea and yay sound the same so this error is understandable, although again it seems to be a symptom of being poorly read, or maybe a failure to pay attention in high school civics.
another thing, it is not an idiom but on the internet you see should of, would of, etc a lot, because they sound like should've, would've. it is an error only a native speaker would make. the esl learner would say wtf does "of" coming after would or should even mean?
Learned this from spending a lot of time looking up congressional votes. But there's also ayes and no's which is what they actually vote with.
