Why are some 質問 on ファンポップ where they aren't answered for a long time?

It's either the 質問 is stupid, または many people are offline, that's probably why.

The 質問 is dumb and possibly weird..

People probably don't know the answer to the 質問 または just don't want to answer it.

It depends on the 質問 actually.

Not all 質問 will get around to being answered あなた know. There are several reasons that one might not get answered.

It may be the question, it may be the time it was posted, it may be people being in active, it may be something no one knows, it may be a spam question, several reasons.

Cool story bro.

Probably Because They Don't Know The Answer,Someone Else Gave Exactly The Same Answer,They Don't Have An Opinion Over The Subject または The Same 質問 Has Been Asked Over And Over Again !!!!

People are lazy that's why.

because its retarded and stupid thats why pretty obvious

It's possibly a spam like this one:

Some 未回答 質問 are ether nonsense, annoying または not interesting to answer. We had some people trolling and making dumb 質問 in another language like this: أكره الجميع

あなた blew it people. あなた weren't supposed to answer this.
Yeah, I'm a hypocrite.

It's sometimes a very inappropriate 質問 to answer, like "what's the size of your pines" または something.
