Why are some 问题 on 潮流粉丝俱乐部 where they aren't answered for a long time?

It's either the 问题 is stupid, 或者 many people are offline, that's probably why.

The 问题 is dumb and possibly weird..

People probably don't know the answer to the 问题 或者 just don't want to answer it.

It depends on the 问题 actually.

Not all 问题 will get around to being answered 你 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 或者 The Same 问题 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 未回答的 问题 are ether nonsense, annoying 或者 not interesting to answer. We had some people trolling and making dumb 问题 in another language like this: أكره الجميع

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

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