Anyway, since all these big corps are famous for not listening to users' feedback, you'd just have to bear with it if you insist in using their services. Having said that, you might want to make the Spam folder a little bit more comfortable to work with. And to do that, you need to facilitate the "Filter Settings" feature.
What we did was to create filters having emails from certain spammy domains to be thrown into Trash immediately. This does not solve the problem from the root, but it does make your Spam folder looks cleaner so that you could locate your email easier and faster.
We have also prepared a list of domains that you might want to filter as they are proven to be spammy. But you will have to create the filters manually one-by-one since the tool does not offer any bulk import support.

(Note: we will be updating the list from time to time)
We do hope this helps a little in managing your mailbox.
