This is a very simple method that worked 9 out of 10 times in the last 2 years with dozens of sponsors.
Check their Copyright year in FOOTER, right now, I would say that if they didn't update the copyright footer, and it says 2007 or sooner, they are probably in danger. It shows that they didn't even care to update that simple footer, and that they don't have at least 1 free minute in a full year to take care about the program.
Yeah, you can laugh and insult and quote me and makes jokes, just make sure you keep laughing when they close the sponsor and don't pay your money, and run away.
Alerts are: ? 2007, ? 2006 or sooner.
Fine is: ? 2010 ? 2011
Medium: ? 2008 ? 2009
You will see most webcam sponsors that are doing U$ 1 millon or more per month, have 2010 or 2011, which is obvious, because their webmaster checks their GOLDEN Chicken every few mins...
While all obsolete dead sponsors have 2005 or less...
