This is actually rather easy to solve without ML/AI. They need to track the change delta (ex: with jsondiffpatch) and weight each part, presumably using levenshtein or text mining with weighted dictionary, and limit changes to 2 or 4 in 24 hours period. Then weekly compare those changes and treat the highest one as need to be reviewed by customer. Additionally, each customer review should tied to specific change version, that they can easily compare with current one.
