We have a zero-tolerance policy against illegal pornography.
Currently IP4Play has five ladies available online, although at the time I wrote this none were actually available for a call.
As Cult of Mac reported, you can buy blocks of time (5, 10, 20 or 30 minutes) starting at US per minute.
Another aspect that makes us unique is the speed at which webcams load.
On some chat sites, you often must wait a long time for each webcam to load.
