my guess would be they like the face to face international webcam chat option and some of them like that the mods gets rid of the obnoxious predators so they don't have to worry about have lewd proposals and may find some intelligent conversations or just some human companionship. Those I don't mind so much.
There are of course trolls and obnoxious predators. However the mods are pretty good at booting them when they reveal their true motives in joining.
anyway the Truth?
1 Corinthians 1
18 For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. 19 For it is written:
“I will destroy the wisdom of the wise,
And bring to nothing the understanding of the prudent.”[a]
20 Where is the wise? Where is the scribe? Where is the disputer of this age? Has not God made foolish the wisdom of this world? 21 For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe. 22 For Jews request a sign, and Greeks seek after wisdom; 23 but we preach Christ crucified, to the Jews a stumbling block and to the Greeks foolishness, 24 but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. 25 Because the foolishness of God is wiser than men, and the weakness of God is stronger than men.
