Seriously, why would someone come to a category in order to ruin it intentionally?

Question

What do you suppose their motivation to be? This happens a lot in Polls and Surveys where people usually have fun. And the spoilers last for months on end. It honestly perplexes me.

Answer 1

Most likely it gives them a sense of power and control.  People who need to feel important and are unable to do this in a positive way will resort to negatives.  After all, negative attention is better than no attention.  It's just the nature of human beings.

Answer 2

Dissent is healthy as it exposes one to alternative viewpoints.  It's how we expand our minds.  I don't care to preach to the choir.

As for the tools who purposely play devil's advocate:  they are also useful in developing a thicker skin, sense of humour etc.

Don't worry about them.  They are always going to be around.
