I keep getting a lot of “Mysteriously Unnamed” accounts when scanning through large follower bases (users with more than 1M+ followers). They all return an empty “screen_name”, and I took a few of those and investigated with other Twitter tools and saw that these accounts are accessible through the web on Twitter.com and are all named “Mysteriously Unnamed”. I’ve found a bug discussion from March 2011 on this but it was never followed up once a request was posted that you guys at Twitter should be notified about more of these accounts.
Just wanted to ask for a quick public update on how to deal with these accounts. Skip and treat as non-accounts? There are many! The issue is that each one of them takes away at least one API call and rate limits is still a precious commodity.
