As other comments have pointed out, not having the subscribers list is my non-negotiable terms if someone wants to take over. In fact, after I refunded everyone, I'll reset my server and remove all my DB backups so I won't even have a copy of it.
I know it doesn't make business sense for someone to buy a business without any customers. That's why I never explore the option of selling it.
