I would think anonymous contribution is likely to yield more truthful information.

It (by design) includes only people who self-select to share their compensation details. I would expect that to skew high, even if 100% truthful.

what self gratification does one get by boosting his/her salary when it's anonymized?

I didn't argue they're likely to boost their salaries, or that they receive self gratification from doing so, so I'm not sure how to answer your question.
