It seems there are some users who think that the wink wiki entry should be updated according to the discussion in the comment section of post #1617965 (explicit). By doing a search of "wince -wink" and looking at the results, it does seem that users have not been tagging many wince images with wink as well even when the character does close one of their eyes. My current thoughts on the issue are pretty much summed up in my comments on the linked post.
