There's a thread in general forum about the new raid started by a user who created their account in January of this year with less than 150 posts. They have a custom avatar. Why does a new account get custom avatars but an account as old as mine with 20 times as many posts does not?

Also, Why does said user also get to have a signature with an animated image larger (850x200) than the rules state (350x125)?

Edit: They also get a custom title too.
