Twitter Shares Soar after Second Quarter Earnings Results
The social media site has filed a report saying that 23 million active Twitter users are actually bots. IBTimes UK

Around 23 million active Twitter users – 8.5% of all accounts – are run not by humans, but by robots, says a new filing by the microblogging company.

The company is revealing the information to "clarify who on Twitter is and isn't real", it says.

The filing, made to the Securities and Exchange Commission (SEC) by Twitter, shows that sophisticated algorithms actually run far more accounts that anyone previously imagined – many of which are indistinguishable from human-operated feeds.

This means it's likely some of Twitter's 271 million active users have interacted with a Twitterbot at some point during their time on the site, and many will have followers that are bots designed to generate buzz for a company or product or that have been created solely to increase a user's follower count.

Bots are different to spam accounts, which simply flood users with tweets and links to dubious products. In fact, some bots do the world of Twitter a public service by disseminating public service information. Many news organisations use algorithms to tweet their latest stories for example.

And some are just for fun. Here's our run down of the best Twitter bots:

Twitter
@Betelgeuse_3

@Betelgeuse_3 automatically responds with "It's showtime" every time a tweet references 1980s film Beetlejuice.

Twitter
Twitter @EnjoyTheFilm

@EnjoyTheFilm ruins films and TV shows for users who have tweeted that they are watching a particular show by giving away the ending.

Twitter
Twitter @tofu_product

@tofu_product gained a swarm of press coverage, including a write-up in the New Yorker, for its clever way of imitating users' pattern of speech and 'speaking back' to users who tweet at it.

Twitter
Twitter @YourMomBot

@YourMomBot does exactly what you would expect it to. It adds "your mom" to the start of random tweets and tweets them back at the user. Sometimes they work, sometimes they don't.

Twitter
Twitter @AllTheCheeses

@allthecheeses finds its genius in its simplicity and simply retweets any tweet with the word "cheese" it.

Twitter
Twitter @YesYoureRacist

@YesYoureRacist ingeniously counters people who tweet the phrases "I'm not racist bu…" and "#notracist" by retweeting their comments under the banner: "Yes, you're racist".

Twitter
Twitter @RedScareBot

@RedScareBot brings back the ghost of Senator John McCarthy in Twitter form. If you happen to mention "communism" or "socialism" on the site, this account will tweet back at you with 140-characters of vitriol and call out the "Red Storm Rising".

Twitter
@Horse_ebooks

@horse_ebooks is undoubtedly the most talked about bot on the web, as bloggers and journalists have dissected the account's tweets, and someone has written a book of poems inspired by the account. There's no rhyme or reason to this bot's tweets except an earnest, misguided aim of selling low rent horse-themed e-books.
