ALL is sending Spam to my account via BCC and their site will not allow me to cancel AOL.

Sadly, nothing in life is truly free; there will always be a cost…

Many of not all “free” services are monetised through advertising - and delivery of email that many consider to be spam. Often the only solution is to use a “paid” email provider, ditching the free account. It is unusual that you can’t terminate an account with a provider - but if you have difficulties, you can simply abandon the account and delete the account from your devices:

Settings > Mail > Accounts > [Your AOL account] > Delete Account

Ne aware that signing-up for online services, newsletters and some websites can result in you receiving unsolicited email (i.e., spam) - regardless of using a free or paid email service.

This is a user to user only forum, in case you thought you were speaking with Apple here. We may agree with you, but then we don't have anything to do with AOL at all. And Apple doesn't own AOL at all. We also ALL get spam messages as it has become a fact of the digital life today. Just throw the message away is the only advice anyone here can give you.
