So, if you want to use this script, go ahead, but be sure you know what you're giving up in exchange.
Finally, I'd also recommend you know with whom you are dealing. Is it someone you trust? The Terms of Service claims you are dealing with "BZO Technologies Group", but (as you'll find out if you try to look them up), that's just a shell corporation, located in a Delaware mailbox with hundreds of other "corporations". Who is actually behind the shell is anyone's guess.
