It is pretty scary, but people are always welcome as long as they do productive stuff. And I usually ignore people's contributions if I read their editing description and it says something positive.

If someone says that they're fixing some grammatical errors, and they remove over 5000+ characters of text and replace it with gibberish....then that's not productive.
