Are Spammers killing Twitter? Despite constant upgrading, Twitter is more often down than up. 
Spammers like this one don’t help - “she” was following over 1000 people when she started following me.
“She” has just one entry. It links to a scam website that sells the concept of Water as a power source for your car. Numpties.
None of this is new of course, but it is sad nonetheless to see a great company like Twitter get hurt by unscrupulous idiots like these.
Twitter also sits on the Amazon S3 cloud. This has been the subject of a few recent outages… http://www.geekzone.co.nz/foobar/5435
