This has a rather colourful collections of reasons: http://whatjapanthinks.com/2011/07/11/wh...n-twitter/
Q: What characteristics make you want to stop following someone on Twitter?
1 Lots of aggressive tweets 100
2 Sequences of shifty tweets 75.2
3 Sequences of drama queen tweets 72.1
Edit: Looking at the original, it seems #2 refers to Japan charity type stuff, and #3 might better be translated as ‘attention whore’ rather than ‘drama queen’—a subtle but important distinction. ^_^
