I didn't yet do my introduceyourself post. When I will, to prove I am the guy in the pictures I will indeed share social media accounts that validate that.
As a personal action, I don't upvote posts on Steemit that don't have that, otherwise how can I know they're really who they are. For example this babe: https://steemit.com/introduceyourself/@devyataeva/hello-steemit-my-name-is-elena-nice-to-meet-you
I didn't upvote and apparently 3h passed and 95 others did, but none from the serious league that would give her real money. Because real people know it has high chances of being fake.
I see, well I don' think this way I'm verifying my identity and for the record posting other social accounts could also not be the way. If it is so important to verify your identity then I think Steemit or the blockchain should do it, have it done at registration. I really don't have the time to check every user to see if it's a bot or not...I do try to check the post to see if the content looks legit.
I upvoted that babe (although it has photo "verification") but looking at "her" past posts it's clear that it's a spammer. Unvoted.
