People could say things like “God, what a load of malarkey” and it would be beyond many parsers to interpret.
What do they do when someone posts something which actually is profane, without using any of the preprogrammed “profane” words, like “God” and “Jesus?” What if a pedophile makes sexually explicit comments, without using any “profane” words?
If they’re willing to risk comments like that being posted, and then presumably deleted by management, why can’t they risk the possibility of a child saying they are thankful for God on a thread where Disney asks them to say what they’re thankful for?
The problem here isn’t that they block profanity. The problem is that they identify God as profane.
