There are middle grounds. I have a myriad of servers that accept email for any domain as fast as the spam bots can send it, meaning the bots will detect them as open relays. Some bots use tracking codes back to themselves to confirm the relay is indeed open but many do not. The SMTP prompt even says not to use it. Some spammers eventually catch on and start trying poorly to attack my nodes which leads me to believe most of the spammers are not very technical.
