Why are some các câu hỏi on fanpop where they aren't answered for a long time?

It's either the câu hỏi is stupid, hoặc many people are offline, that's probably why.

The câu hỏi is dumb and possibly weird..

People probably don't know the answer to the câu hỏi hoặc just don't want to answer it.

It depends on the câu hỏi actually.

Not all các câu hỏi will get around to being answered bạn 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 hoặc The Same câu hỏi 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 chưa được trả lời các câu hỏi are ether nonsense, annoying hoặc not interesting to answer. We had some people trolling and making dumb các câu hỏi in another language like this: أكره الجميع

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

It's sometimes a very inappropriate câu hỏi to answer, like "what's the size of your pines" hoặc something.
