twitter is one of the richest companies in the world and can easily afford to hire staff to find inappropriate accounts to report and suspend but why bother when there is plenty of slacktivists that will do the job for free.
Such slacktivists are too dumb to realise they are being exploited.
Such people are known as twitters bitches.
Similar to the word "jitters", the twitters indicate a form of social intensity symptomatic of someone posting tweets far too frequently on Twitter. In adjective form, "twittery".
"Richard's posted 45 tweets in the past hour - somebody's got the twitters."
"Sheila's got a proper case of the twitters - she's updated damn near 100 times since lunch time.
