Account Termination for Trademark Infringment?

I am a small independent publishing house specializing in print paperback workbooks for educational test prep. I have 40 plus titles, sold about 1,500 copies last month, and we are scaling our catalog aggressively averaging 15 to 35 SKUs per test across multiple editions.

Due to the nature of the business, I need to mention specific exam names in [ideally] the titles, but even subtitles only would work also mentionining the test name in the covers, and descriptions to reach customers. Parents will not search for generic workbooks. I always include disclaimers stating no affiliation or endorsement. Should be totally allowed under the fair usage law. [I.E. Test prep for the SAT]

But I moved from KDP to a third party aggregator and the aggregator removed 10 listings all at once over a claimed trademark issue from Amazon, but they would not share any details or documentation. I suspect it was their preemptive call, not an official enforcement. I am now transitioning to Seller Central because there are many limitations with KDP and the aggregator I am using, and I am anxious about platform risks.

With my high volume setup, where i need to mention exam names and doing it for 20-30 SKUs, I am worried that if trademark claims hit multiple listings at once, it could lead to full account termination and lose years of work. Has anyone in test prep dealt with this? How do you navigate nominative fair use, prepare for mass complaints, or mitigate suspension risks?
After suspension, is there a real chance to get the account back? I’d be fine with removing the asins and not sell these asins anymore, I just want to keep selling on amazon. I am the author and 100% of my content is original, I have disclaimer in the description, book cover, and copyright pages of the books.

Any success stories or tips would help. Thanks!
