Gonna be real with you ghosting AMs is a pain but I found a trick that sorta works. When they go dark I send a follow up email with a screenshot of the recent CPA spike I got from the offer and a quick line like hey just wanted to check in, I see good numbers and want to keep pushing. Usually I get a reply within 24 hours and they start giving me more info or at least a bit of life. Last week I did it and got a reply from a top AM promising a exclusive offer next week if I keep the numbers up. Cope but it's better than silence and I've closed a couple deals from it sooo far.
