While the comment seems to be ownCloud related the user name / URL points to something like an essay writing service where it looks to me clear that this only has the purpose to advertise for this service.
The easy answer is that i wasn’t sure / known to who is responsible for maintaining the blog posts
One problem i’m seeing here is also that not everyone has this knowledge and an additional account on central to report this.
But maybe the CMS behind the blog post engine is already able to provide a reporting functionality and it isn’t enabled? This would make such reporting way easier and doesn’t require the knowledge where to post this.
