Thoughts Number

The user is underage so it automatically disables but that only happens after a specific update, and they commented before that

They commented before the user disabled comments

Well its automaticly the comments are disabled even though the creator didnt not disable it because of the update that users that cant comment and cant use other feature like texts, textbox and others and when they upload a deck, it automaticly disables the comment even when they uploaded the deck before the update.
