The DNCL continues to receive heavy criticism, the latest being from Senator Percy Downe who referred to it as "totally useless", due to the costly but totally ineffective enforcement, the large number of exempt groups and the ability for anyone from anywhere in the world to purchase sets of phone numbers for relatively low fees, and then abuse the Do Not Call List as a calling list. Senator Downe cited multiple examples of constituents, whom he had personally added to the list, receiving a sudden increase in telemarketing calls three months later.
