couldn't they do a reverse image search, see that it is already online, and therefore suspect that it was not posted by the person it depicts, and therefore require the verification? I don't see how "posting a picture you got from google images results in them asking you to confirm that you are the one in the picture" indicates that they generally require verification before you can post a picture of yourself. I mean, based on the name, I assume that in my case that subreddit wouldn't be interested in a picture of me, because I'm male (and, I also wouldn't want them to have it either), but still.
