Are you saying he bought the 10 upvotes? I interpreted this post as being a 'whistle-blower' type of post, i was not aware that people was buying votes, and it will definitely cross my mind when evaluating future posts.

I dont see a reason to flag/downvote this post, since the author is, in my opinion, informing the community about this type of abuse, rather than endorsing it. Issues like these demand attention, not only from the core developers, but from all of us.
