MrEyeballs29 presuming you have the necessary permissions to install browser plugins, you could do that (and automatically hide the words for yourself, and anyone viewing your computer) instead of trying to persuade Greg to change his habits. For Firefox, I very quickly found one called "Advanced Profanity Filter", and if you're using a different browser, I expect you could still find something similar.
Umm I am using Chrome but thank you very much. Also trying to change to blue texts does sometimes way too. finally I don't have to change any profanity words into with just using blue text.
