myPHPNuke 1.8.8_8 has a complete renewed mechanism for preventing your users from using foul language aka bad words. A list of bad words with their replacement is provided with the distributionkit. It only contains American English words, so you might want to extend this list with your own words.

The list is contained in the file censor_list.csv in the root directory of your website. You can edit it through a text editor or through a spreadsheet program on your local machine and upload it to the root directory of your website.

It has this format:

			
bad1,good1
bad2,good2
bad3,good3
