Sir, I tried to understand some parts of your post but couldn't, especially the area I bolded. If you can throw more light in that particular area, I'll appreciate.
Seems quite straightforward. If you submit by twitbook credentials (if I had any) to some random bounty, it may not mean that I'm your alt. But if whoever is in control of those social media accounts starts posting for that bounty, that's a much more solid connection.
