Apple-ID disabled daily - clueless people cause it, but can Apple fix it?

Question

I have a particular problem with an Apple-ID belonging to a family member. Her Apple-ID is disabled almost daily, forcing her to unlock it using two-step verification (a trusted device and her Recovery Key). Sometimes - unclear why - unlocking isn't possible, forcing her to change the password everywhere.
There's a particular reason for this, we suspect.
She has an iCloud/MobileMe/.mac/iTools-address from way back. It's a really nice adress, consisting of just her given name followed by @mac/@me/@icloud. Problem is, her given name is quite common in the world. It would be totally impossible to get an address like that today, you'd have to be one of the first signing up for iTools in 2000 to get it.
Nevertheless, quite often people with the same given name seem to think they've managed to sign up for it. So they hand it out to friends, sign up for newsletters and services, and try to login to it themselves. And as a result, Apple disables the password - presumably after a certain number of login attempts.
I'm totally confident the broad majority of these shut-downs aren't caused by malice. I'm pretty sure the account has never been compromised. It's just people - and many different persons, in many different countries - with no clue at all, trying to login and/or resetting the password. There are many, many stray emails, iMessages and even FaceTime calls from total strangers that supports this theory. It is actually people thinking they managed to get that address and Apple-ID. You'd think it is impossible to not notice the "that Apple-ID/iCloud address is already in use, please choose another" messages but... Judging from the emails and iMessages, the majority of intended recipients speaks Spanish, so maybe its a language problem.
This always intensifies after Christmas, as millions of iPhones and iPads get into the hands of newbies.
We thought it would get better after enabling two-step verification; that it would make it harder to force a password reset. But after the past holidays it has accelerated to insane levels.
An Apple-ID is today used for so many things that it is really important that it stays active. Someone causes it to be disabled = you don't get any iMessages, for instance. Or, suddenly all of your calendars are gone from people you share them with, as they can't access them either. And you usually won't notice anything's wrong until you go to iCloud.com and try to sign in.
I guess this happens to all people with Apple-ID:s or iCloud addresses like [email protected] or [email protected]. Is there anything Apple can do to prevent this? Is there anything we can do, besides abandoning this Apple-ID?
We have reported it to Apple using various forms, but no replies.

You don't have to abandon the Apple Account rather you can get a new, less common, email address and change the email address identifying the Apple account to it.

No, you can't. The OP's Apple ID is also the account's @mac.com address since she goes back to iTools, and while if an Apple ID has been created using a non-Apple email address it can be changed, if it's the @mac.com etc. address which is also the iCloud primary address it can't be changed. In this circumstance (which has been a problem for a number of people) that restriction is rather a nuisance and it's difficult to see a way round this.
@Jan Rendall: I don't know what method you've been using to contact Apple, but I would regard this as a serious security issue and that's the approach you should take. This Apple Help page provides contact information for various countries for security problems with an Apple ID:

The ideal would be for Apple to arrange for the ID to change to a non-Apple address (have one available) - this would solve the login problems though not the daft emails - I've no idea whether they are able or willing to do this, but if you don't get a good response at first ask to escalate it to a higher level and dig your heels in. What is odd about all this is that 2-step verification should have put a stop to this since without the code which has been sent to the trusted device a person trying to log in cannot proceed; you should raise that point with Apple.
