I don't save anything on cam4btc.com, but one of the girls donated a Bitcoin to the vanity address https://blockchain.info/address/1Cam4BTCM9pWWcyEd6GLEKTocQfRsQy5fP so I'm sure it is fine to link to it. Here you can see the kind of donations being made: https://blockchain.info/address/1GbALXTp6UbWTdrodMEk9SM57NokR6yhiZ
The action in the site has dried up because I have no time to actively advertise it myself. I, however, also don't charge besides donations and keep the site up so you can do this yourself. Using cam4btc you can essentially keep 100% of you donations if you take your customers with you and don't donate to the site. People will definitely spend Bitcoin, people don't keep their gold until after their death either and besides, it's quite straightforward to purchase more Bitcoins these days
