Why do people give thumbs down for no reason?

I was looking at a question, about a skirt and people said the link didn't work. There was one person who saw the skirt and had proof. (I could see the skirt, the link worked fine for me. The skirt was called something like "denim scooter". The person used the the name) Then some one gave everyone who could see the skirt a thumbs up and the person who saw the skirt, gave a friendly answer, a thumbs down!!

It happened also with an answer I gave about something else a couple of times. Also an old question I answered, some one asked about a store. I guess I was the only person to know the store because everyone else didn't know.... Then I got like 10 thumbs down! So I just decided to delete my answer....

What's your opinion about this?????

Thanks! :-)

TYPO!!! I ment everyone who couldn't see the skirt a thumbs up. Sorry!!

I don't know...I find it incredibly annoying,too and actually asked this question yesterday but no one answered except SOME JERK haha seriously.

I don't understand how you can give a thumbs-down for something that is basically a FACT...it's not like I'm giving my opinion on something and you don't agree..it's like I'm actually saying "this is how I've seen it done" and I take the thumbs-down as people saying "no you haven't, you're wrong."

...! so annoying

They're power-tripping.

Some people just like playing devils advocate sometimes. I wouldn't let it bug you.

I don't ask "why" here anymore!

Because they have nothing better to do and want to be annoying.

Eh, some people are just strange. XD

They wanna be annoying. How do you kno the guys who gives thumbs downs are the same people with over 50 different yahoo accounts?!

Just because they give thumbs up or down, doesnt always mean they mean it.

I call them the thumbs down bandits. They do it because they can, for the heck of it, for fun, to aggravate you, who knows. Don't worry about it, when normal people read the questions and answers they can tell whose question has been hit by a thumbs down bandit.
