I'd love to see a badge for 'official' accounts, similar to verified Twitter accounts.
When you talk about official verified accounts on a platform where privacy is pivotal, then its not much of a good idea. Facebook-like platforms would welcome that idea gladly.
I'm not saying those account should dox themselves or whatever. There are plenty of official accounts on Bitcointalk (from exchanges, physical bitcoin creators, artist, coin developers etc.). Verifying could be as easy as sending a special tweet (or DM) from their official Twitter account. It might even help combat scammers since there have been plenty DMs sent by imposter accounts.
