Although this subject has come up in a number of different threads here and on the Support forum, I don't recall seeing it explicitly addressed. So here goes:
When the profanity filter for reviews detects a word that is forbidden, it simply highlights the text for the entire review. The profanity filters for forum posts and for messages both highlight the individual words that are triggering the filter. Since profanities vary amongst English-speaking cultures, and since not all posters are native speakers of English, highlighting an entire review can cause confusion.
Please change the profanity filter for reviews so that it will show which words are considered profanities, rather than highlighting the entire review.
