The Competent Authority may direct a person meeting the prescribed criterion, an internet intermediary with at least 500,000 unique Singapore visitors a month (or a website owner or operator with at least 100,000) averaged over any three consecutive months, to appoint a person in Singapore to accept service of directions, orders and notices and to give that person's contact details; failure can lead to access blocking of the service or location. Directions may also be served on an appointed representative voluntarily named (ss.14, 26, 41).
