For everyone wondering, this one is mostly a joke. Depending upon how much spaghetti code the code for imgflip is, this may not even be possible at this point.
You should have quality control on names to prevent curse words or otherwise inappropriate names to make the site more family friendly. For example, I’m literally named ‘Piss.Man.2’ and there is another person named ‘TheRapist.’ There was also the trend of names following “killyourself” a little while ago. Granted, these names can’t be used again but variations of them can.
