Hi everybody, Yesterday, I found something extraordinary when I was solving problems 327A — Flipping Game. When I scrolled down to the contest material 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)

When I open the inspect mode, it exactly appeared the link is redirected to www.google.com (like under the picture)

So my suggestion is: Why do we not remove those useless contest materials from the contest materials box? For example, maybe some users like me, want to read the tutorials but misclicked into those useless links.
