	 * Introduction to Tinyboard's spam filter:
	 *
	 * In simple terms, whenever a posting form on a page is generated (which happens whenever a
	 * post is made), Tinyboard will add a random amount of hidden, obscure fields to it to
	 * confuse bots and upset hackers. These fields and their respective obscure values are
	 * validated upon posting with a 160-bit "hash". That hash can only be used as many times
	 * as you specify; otherwise, flooding bots could just keep reusing the same hash.
	 * Once a new set of inputs (and the hash) are generated, old hashes for the same thread
	 * and board are set to expire. Because you have to reload the page to get the new set
	 * of inputs and hash, if they expire too quickly and more than one person is viewing the
	 * page at a given time, Tinyboard would return false positives (depending on how long the
	 * user sits on the page before posting). If your imageboard is quite fast/popular, set
	 * $config['spam']['hidden_inputs_max_pass'] and $config['spam']['hidden_inputs_expire'] to
	 * something higher to avoid false positives.
