Can anyone block those who reply on Yahoo Answers using the power of non-sence?
You can only block 200 people and most of the users you see selling and spamming are going to be removed by the next day. What you should do, instead of uselessly blocking them, is report their answers. It’s a great way to improve your trusted reporter status (just don’t abuse this) and get the junk content removed. Never respond to the spammers or trolls. Just report and move on.
