CAUCE joined a group of major consumer, privacy, and anti-spam organizations, in calling on Congress to abandon the current crop of pro-spam, anti-consumer legislative proposals that it's currently considering in that the measures being considered by Congress are too weak because they don't actually prohibit spamming (merely require an opt-out), and don't allow consumers to sue spammers.
CAUCE also released a separate statement calling on all Americans to let their representatives in the House and Senate know that none of the currently-pending legislation is adequate.
CAUCE is an ad hoc, all volunteer organization, created by Netizens to advocate for a legislative solution to the problem of UCE (a/k/a "spam").
