What is wrong with this sub?

This sub has 1.1 million followers, it should has really well thought out answers when I ask an innocent question.<br><br>Instead I get a large number of low effort replies like "This" , "Same" and "Holy shit" that don't make sense. <br><br>I even get people posting pictures of their feet and asking me if I like it. <br> <br>Why is this sub so filled with idiots and trolls?
