The blog was created in response to a vandal who did exactly what was described: showed up over and over again under new accounts and immediately requested admin rights. On a couple of wikis, the inexperienced admins and bureaucrats didn't know it was a vandal asking and weren't aware of the harm that can come from giving out user rights. It did take Fandom staff getting involved to fix that problem.

So, the blog is to provide advice to help people see that they should be careful and evaluate requests instead of just going ahead and saying yes.
