So, let's say that I have a big google spreadsheet that multiple users have access to, and I'm not able to control which users have access to it. I have a concern for trolls. If I wanted to prevent people from entering certain words, specifically slurs and curse words, how would I accomplish something like this?Something fancy with regex in the form? I'm not familiar with Google Sheets and what I've searched up online hasn't helped me.
