It is a valid issue/problem that is actually already in the works and should be completed soon. We were kind of doing something like that already a while back – sending the automated emails to our mailbox for these types of issues/problems. So we will implement that again, add some more stuff and cc ourselves in the automated emails.
Without boring you with all the technical details, BPS Pro is designed so that all user initiated actions/requests are outgoing POST requests from your website/BPS Pro to the API Server for all the right/correct ethical reasons – privacy, etc. So in order to do an Activation Key check from within your site / in the BPS Pro code, we would have to include the Salt we use to generate the Automated Encrypted Activation Keys, which would expose that Salt publicly so we would not want to do that.
