OK I have heard many people saying that they have had issues with Adsense on their sites and, or even had their accounts suspended without understanding why .....
The thing for Google Adsense is that they have many conditions they expect webmasters to comply with!!
Im not joking either and once sites are found to be breaking these conditions the penalty can be suspended accounts and all your earnings returned back to the advertisers.
From what I know about 90% of Dolphin sites are dating / adult based sites containing adult contents and chat rooms ....
Some of the things I can tell you right now is that 'adsense' in chatrooms will get your account suspended if discovered by the 'Big G Team' ... Another thing that is major and will get your account suspended is have the 'site menu/navigation' being set in a way that it causes it to over-lap 'adsense' and in-turn cause un-wanted clicks.
some of Googles conditions include;
NO adsense on Pornography, adult or mature content sites
NOT Place misleading labels above Google ad units. For instance, ads may be NOT labelled "Favourite Sites" or "Today's Top Offers".
NOT Displayed in pop-ups or pop-unders.
NOT Placed in emails, email programmes or chat programmes.
NOT Obscured by elements on a page.
NOTPlaced on any non-content-based page.
Sites showing Google ads should be easy for users to navigate. Sites may not change user preferences, redirect users to unwanted websites, initiate downloads, include malware or contain pop-ups or pop-unders that interfere with site navigation
NOTE; the Bold condition above ! This is meaning that adsense is not allowed in ANY CHAT ROOM whatsoever under any condition..... IF YOU HAVE ADSENSE IN YOUR CHAT, EVEN FOR YRS AND NOT BE IN TROUBLE ABOUT IT > BEWARE AS YOU WILL BE !!
Google will suspend accounts with adsense at chat rooms /dynamic content pages due to them not being able to monitor what is happening in chat rooms and also chat rooms do not contain contents that google understands ... Google insist what their adsense is only used on pages with contents.
I hope this helps some of you from having issues with Google Adsense ..... I have personally had issues with them and its not nice!
I was lucky to understand their reqiurements and make changes allowing my Adsense to continue with out further issues... ALOT OF PEOPLE ONCE CAUGHT WILL NEVER GET A SECOND CHANCE.... SO BE CAREFUL AND MAKE SURE YOU READ AND UNDERSTAND THEIR REQUIREMENTS !
