As for "mama" let's just blame the oders for obvious reasons.

Gibberish, because people can workaround with different letters to make it appear as an inappropriate word or something like that.

As for why it's so strict, I guess it's cause they don't trust children not to make foolish choices. And I can't say they're always wrong.

It's also strict so they don't have to see what the people over 13 might be writing, because at that point they may try profanity or other dirty references.
