I haven't opened a new thread to ask a question in a while, but as far as i know, if you check the box "this is a question" you get an additional warning that posting it in any other section than q&a is a rule violation and one has to confirm to actually post it.
that means that those people clearly violate forum rules after being warned about it. in some devices' sections, threads like that are deleted without further notice, because the moderators don't see themselves as maids for lazy or impudent users.
also, it should be noted, that posting problems, bugs or hardware issues also counts as posting a question.
that means:
- hardware issues should be posted in existing threads of the same issue and for every broken button, the bezel, the display and the battery there already is at least one thread in Q&A.
- hardware issues with accessories should be posted in the accessories section (also in existing threads, where applicable).
- problems with certain apps can be discussed in the themes and apps section, if they are published there, or in Q&A, if not.
- problems that apply to specific roms only should be discussed in the rom's development thread (except for CM), if that helps getting rid of bugs.
If you are a new user that does not yet have the permission to post in development, search if the bug or problem you want to report is already posted, if not, you can either get to the post minimum (without spamming!) to post there yourself or ask in Q&A.
It is so easy and self-explanatory, I don't see, why people keep breaking those rules.
