welcome & upvoted. nothing wrong with being anonymous here.
the "verification" (posing with a piece of paper with steemit written on it) is only asked when someone presents himself with an identity and personal photos, to make sure it is really him and not identity theft. and it's not mandatory. that person though wouldn't be likely to receive any upvotes if he cannot prove to be the person he claims to be.
if you come with no face , you obviously don't have to confirm to be anyone
