lol - it's sustainable because it's not a BUX site and does not rely on ponzi revenues to stay afloat like most other PTCs anyway, the ponzi model crashes really quick, usually lasting few months.

You should never compare "REAL" PTC model to fraudulent bux and ponzi referral / upgrade sites.

One thing where CS shines compared to PTC is the type of advertisers they accept. Unlike many / most PTCs, CS does not accept HYIP, Matrix, MLM, etc........a #1 source of scam. Some multi hundreds of millions scam HYIP have used another well known site to advertise to and I was one of those victims of this f****** scam.

CS earns its respect by cutting away from disgraceful, good for nothing worthless scheming waste of DNA CROOKS scam artists that roam the internet (Richard O'Neil and his other aliases and other sites.......under different names) etc..... That's a good thing. PLUS CS is also a full fledged GPT, so you can earn mone here without investing a cent and without referral whoring ))
