What does the error "this word doesn't count" mean? Should the word be countable? Is it known (because "I don't know this word" also exists as an error) but not on the top N list?
I also got "this word doesn't count because it's too common" as well as the separate "this word doesn't count" - seem to have a few different exclusion reasons, some of which don't have an accompanying error detail.
Oh, right I can see how that could be the reason for the word I tried.
