User blog comment:Sannse/How to Block Someone in Your Community the Right Way/@comment-31916334-20160808153204

I had a vandal attack on my wiki once. I blocked the person for as long as possible (I was tired at that time) And then they made a sock and did the same thing. got that one blocked sometime he asked an admin about the block on his original account she didn't know so I told her that that was a sock of the original user and that he was created pages unrelated to the wiki. They kept doing this (this = making socks and ruining my wiki) and I was tired of this happening so I reported the issue on the chat here and everything was fixed.

And that's how I learned that blocking for the right reason can be bad/good!
