My understanding is that something among those lines happened:

> All Policy A (no LLMs) reviews that were detected to be LLM generated were removed from the system. If more than half of the reviews submitted by a Policy A reviewer were detected to be LLM generated, then all of their reviews were deleted, and the reviewer themselves was removed from the reviewer pool.

Half is a bit lenient in my view, but I suppose they wanted to avoid even a single false positive.
