The reason why steemians would like to see some verification is that we have seen many fake accounts here. Impostors are trying to make money by claiming that they are some public figure and copying their texts.

No need to take any pictures, that's only one way of verification (and not even very good because images can be photoshopped). At least one person on the comments has emailed and verified you so that's enough for me (if somebody is still suspicious, they can email you too).
