Noah Kravitz built up quite a following at PhoneDog, a mobile-phone news and reviews website. By late 2010 his @PhoneDog_Noah Twitter account had amassed more than 17,000 followers. That was all well and good, until Kravitz resigned and went to work for a competitor. Kravitz took his followers with him, changing the name on his account to @noahkravitz. And that's when PhoneDog, which was unwilling to let 17,000 fans go that easily, filed a lawsuit against him.
