As you know, Google has stepped up disabling and banning AdWords advertisers. The bans result in the advertiser not being able to set up new accounts and Google is stricter about who they ban. In fact, I am getting phone calls and emails from people complaining to me that their accounts are banned (I cannot get accounts unbanned, so please do not call me).
There should be an appeals process, but does it work? I doubt it.
An old Google AdWords Help thread has been updated by AdWordsPro Bindu. Bindu said, in black and white, plus bolded a sentence:
My answer to that would be almost never will account be unsuspended. Once an account is suspended, its hard to get details on the exact violation (I, for example, have no insight as to why accounts are terminated). That said, it almost doesn't matter, because once an account is suspended, Google reserves the right to terminate all future advertising with AdWords.
Got that? It seems like the appeals process won't make much of a difference. As Bindu said earlier in that thread, "though I would not want to raise your hopes, I recommend you write in to support for a re-evaluation of your account. They will be able to follow through with a final word on your account status." Good luck.
Again, I feel bad for those being banned - but I personally cannot do anything for you, so please do not call or email me.
