Hi everybody,↵
↵
Yesterday, I found something extraordinary when solving problems [327A — Flipping Game](https://codeforces.net/problemset/problem/327/A). When I scrolled down to the contest materials to search for the solution, I found a post named: "try". When I clicked on it, it redirected to the Google main website ([Google.com](http://google.com))↵
↵
When I open the inspect mode, it exactly appeared the link is redirected to www.google.com (like under the picture)↵
↵
↵
↵
Starting from that point, I have come through some of the first contests on Codeforces. And I have also found many tutorial blogs have been deleted or hidden by the authors but are still showing in the Contest Material box.↵
↵
So my suggestion is: Why do we not remove those useless contest materials from the contest materials box? Maybe those blogs only follow the experiment purposes, but it will make some inconvenience for the users. For example, some users like me, want to read the tutorials but misclicked into those useless links. ↵

Thank you for reading my blog. If my blog is duplicated, please tell me.↵

P/S: Since English is not the primary language in my country, I am very sorry for any grammatical or pronunciation mistakes in the blog.
