I would suggest using a combination of: 1. solid, legally-sound T&C 2. require real address, etc with registration - and use a CAPTCHA technique, which may not be nice and accessible but then again when did you last here of a blind man uploading a banner ad image? 3. delay publication of ads until each image has been verified by a human 4. to counter the annoyance of no.3 you could add a 'niceguy' flag to your userdata so that people you trust not to upload pron don't have to wait to be verified. alternatively only allow text ads (works for Google ;-) > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
