Our confirmation process for adding a Twitter account right now requires anyone who wants to add their account to their profile to send a tweet with a small random string. This might be good cause we don’t need to trust the server and seem nice as advertisement, but sending a message out is a very high barrier to entry.
Yes, Keybase does it too but Keybase is also a nerdy tool. Less techy people are very skeptical of posting stuff like this in their stream. We should look into alternatives like doing it via OAuth or similar.
