This is kind of off-topic, why are comments insulting other people's families or religions on Codeforces blogs so frequent nowadays? I know there will always be trolls, but recently I feel like the number of such trolls has increased and they hijack almost every blog and start discussing politics, religion etc. For example, this guy's blog / productivity diary where he was sharing what he did during that week (which I think is a really good thing for Codeforces blogs, and on topic) got hijacked by the trolls: https://codeforces.com/blog/entry/127477, and I've seen a few other blogs too, which got hijacked by such trolls, and got deleted. There were some trolls before too, but recently the percentage has increased significantly.
