Usually availabile on twitter or also known as X (yuck), they are accounts that are automated by other people to post quotes. Most allow you to submit quotes through their submission forms, and some don't really have a submission form.
Most of the quotes that are posted on quotebots are either from existing media or are created by the person who sent the quote. If you really want to know who made It/where It originated from, you can DM the account.
Person 1: What quotebot on twitter do you recommend?
Person 2: Hmm.... holyaches, lostaffections? They are the ones that I usually search through the most!
Person 1: Really? Thanks!
Person 2: No problem! I've also discovered new stuff to obsess over because of the quotebots.
Person 1: That's a smart Idea! Discovering new media through quotebots..
A person, pretending to be deep and philosophical. Quotebots are often seen philosophic verses, without actually understanding them. Quotebots rarely add anything valuable or personal to a conversation.
Guy1: why is guy3 posting “The darkest nights make the brightest stars” with a picture of him at the gym.
Guy2: “He’s a Quotebot, he thinks that this is deep.”
Quoting little more than a famous quote while posting a status on facebook or twitter in an attempt to appear deep and well educated. Also includes posting fragmented song lyrics.
Constantly posting useless quotes on Facebook in order to make you appear more; spiritual, motivated or interesting than you actually are. You're also quite satisfied that you found this quote and can spread your unparalleled "wisdom" with the rest of the world.
"I hate Dave's Facebook page, it's a constant quotebook".
E.g. "If you never go after what you want you'll never have it" unknown
"Happiness does not depend on what you have or who you are, it solely relies on what you think" Buddha
Basically all this kind of wank where people think that posting it on Facebook will change them or change the world… ugh!
