I think the most plausible scenario is the 2010 Dutch film "Vlees," which is mentioned in some sources. The film is about an illegal slaughterhouse and ethical issues in the meat industry. If that's the case, the user might be referring to a story related to the film's promotion or discussions on Okru. However, I need to confirm if there's a known connection between the film and Okru.

Another angle: Maybe "Vlees 2010" is a project or initiative by a specific company or organization in the Netherlands, and the story is about how they used Okru for marketing or community engagement. For example, a meat company using social media in 2010 to promote their products or address sustainability concerns.

Alternatively, could it be a person named Vlees who had a profile on Okru in 2010? If so, the story might be about their activity on the site. But without more context, it's hard to say.
