For those who haven't looked at some of the commits by @pixiuPL, the list is here : https://github.com/ariya/phantomjs/commits?author=pixiuPL.

To summarize: It does not look like the guy has done a single commit with any meaning. His commits are basically the following:

1. Adding his own name in package.json 2. Adding and deleting whitespace. 3. Deleting the entire project and commiting. 4. Adding the entire project back again and commiting.

Just out of curiosity: How likely is that someone may be able to use a large number of such non functional commits(adding and removing whitespace) to a popular open source repository to boost their career ambitions.(e,g. Claiming that they made 50 commits to a popular project might sound impressive in an interview.)
