There is no specific limit on the number of keywords that you can add to your scanner’s Advanced > Exclude all of these words list. However, you may encounter a 500: Internal Server Error if you have an exceedingly large list of keywords. An overload of keywords burdens our server, leading to various issues.

We recommend attempting to decrease the number of keywords in the field in order to fix the problem. You must go over each keyword, remove any duplicates, and look for any syntax issues.
