Fake internet points can translate to real world points. A good blog post can build someone's reputation, it's a sales tool. If you're looking for a better job, or a consulting gig you may seriously consider trying to show your stuff in blog form.
Someone "stealing" your tools without attribution hurt's your internet reputation which can have a real world impact.
It doesn't hurt your internet reputation as much as it gives them fake internet reputation. Which eventually will come bite them back if they try to use it.
It can hurt yours if people think you were the copier.
Steve Wozniak wanted fake points from Homebrew club, I hope you are not using a mac?
