You probably won't need to use all of this but it should be helpful none the less:

var blacklist = ["admin", "webform", "spoof"];
var newAccounts = ["admin1@google.com", "interweb@google.com", "puppy@google.com"];
var invalidAccounts = [];

// transform each email address to an object of the form:
// { email: string, valid: boolean }
var accountObjects = newAccounts.map(function (a) {
    return { email: a, valid: true };
});

// loop over each account
accountObjects.forEach(function (account) {
    // loop over the blacklisted terms
    blacklist.forEach(function (blacklisted) {
        // check to see if your account email address contains a black listed term
        // and set the valid property accordingly
        account.valid = account.email.search(blacklisted) === -1;
    });
});

// filter accountObjects, validAccounts will now contain an array of valid objects
var validAccounts = accountObjects.filter(function (a) {
    return a.valid;
});

// back to the original type of a string array
var validEmailAddresses = validAccounts.map(function (a) {
    return a.email;
});
