I'm just finding it super tedious how people keep repeating the same claims regarding how Google AdSense works without actually looking into it or providing new information. Saying, 'Nuh Uh! AdSense bans are permanent forever! Nothing you dan do! Lies, Lies, Lies!' for the 5,000th time doesn't actually add anything to the conversation.
There are ways you can open a new AdSense account even if you are banned. One involves opening a Google Business account,which would allow you a 2nd chance. It also appears if you change enough of your personal information (address, IP address, the specific computer you are using, etc) you could get a new account approved.

He certainly could have used his parents names, there are many ways he could get around it. Until we have actually information on what he actually did, the speculation and repetition is, to me, just boring thread clogging. Come at me with a link, or your personal experiences with your own AdSense account to qualify your statement, instead of just making a monolithic statement for the umpteenth time.
So far as I understand it Dave has heard back from AdSense once in a form e-mail telling him, 'You filed the wrong appeals form,' and nothing since; so we don't even know if they connected his 3rd 'dummy' account to his original banned account, or if this is a new action. From what I have read AdSense doesn't even take an appeal seriously unless analytical evidence is provided with the appeal, and a YouTube channel doesn't have access to it's direct AdSense traffic analytics to be able to provide, so Dave's 'Wait & See' + send them an appeal that's evidence is just Dave stating 'WRONG! COMPLETELY ERRONEOUS!' is not likely to ever produce a result.
His original account got banned, he was 'confident his appeal would go through because I DID NOTHING WRONG', at some point he created a new AdSense account somehow, he linked this account to his new vlogging channel and KOgaming while DSPGaming was partnered under Machinima, when trying to get partnered under Curse he wasn't able to link DSPGaming to the 2nd AdSense account so he created a 3rd, this was approved for long enough to link with Curse, it would 'do nothing but hurt him' to state the real reason Curse dropped him, upon being released from Curse he noticed his 3rd AdSense account was banned for 'Invalid Click Activity'.
Sorry for whining. Please accept this comedy sketch related to Dave's plans to die in his serious adult GoutHouse come hell or highwater as penance. In DSP fashion it was recorded by pointing a camcorder at a TV
