I wouldn't consider this spam. Spam is an issue about consent, not content. If you had signed up at APWC and given your consent on receiving emails, then that's what you did.
Even at Casinomeister, we have a weekly newsletter and yes sometimes we send out special promotions. We have to pay the bills.
If you want a service, you're either going to have to pay for it directly, or patronize its sponsors. Not much is free - and when it is, you'll usually get what you pay for. J.Todd needs to pay the bills just like we do.
