I have been reporting them to apple and blocking their addresses
That's a waste of your time, money, and storage. Think of it this way, even though it may only take 50-60 bytes to store an e-mail address in a block list, eventually, you will run out of storage. But spammers literally have an infinite number of new e-mail addresses they can create. This is a fight you can never win.
Does reporting them to spam@icloud.com do any good?
No.
Or help Apple update their filters?
It's not your job to keep Apple's spam filters up-to-date and functional. If it were, then obviously you are slacking off. 😄
Either Apple will fix their spam filters eventually, or they won't. If the latter, then spam will greatly increase once the spammers know the filter is down. Then you'll have to make a decision. How much are you paying for this e-mail service? How much money would Apple lose if you took your business elsewhere? Or would your loss of business actually reduce the spam and message load on Apple, thereby saving them money? So what's Apple's incentive?
But that's all just speculation. I can tell you that I pay a small monthly fee for Office 365 e-mail. I get my own domain name and top-shelf, genuine Microsoft Exchange. I just did a test the other day and determined that Microsoft blocks 94% of my spam with 97% efficiency.
