I'm working on building a viral website and I have had adsense accounts disabled twice, should I reapply with a letter to google describing my use Adsense and why i will use agreeing to terms.. Etc Or should I just use adbrite
Adsense will earn more than adbrite for sure, but I guess re-opening adsense account is not up to you.
If you have had Adsense account disabled twice, this means the Google AdSense team found you violating the terms of the service. I would not suggest you to reapply. I would consider you to take your time and come out with a successful model of developing your online publishing. Go with another publisher network and try to get the best of it, without using tricks!
There have to be a reason why your Adsense account got disabled twice. If you have any clue why it happend then you should solve that issue first before reapplying.
The problem is that if you had read the TOS that if you get banned once you cannot legally re-apply, yet time and again people on this forum forget this fact. Sure, re-apply, but technically you are breaking the legal contract you first signed up to. Also if you are re-applying to put it on the same site then forget it, don't waste your time.
if you have been banned for twice, i worry you will get ban again and again, better stick on other PPC advertising program such as adbrite
