Hmm, I thought this was a little strange. I was banned from Adsense about a year ago for click fraud. Since then I have sent probably 10 apology emails to let me back in but with no response. Since then, I created a new website and got a new internet connection and IP address. I reapplied for Adsense and used a different name, different website, and different IP address than from when I was banned, the only thing that is the same is my home address. I recently found out I was accepted, so just put it on my site. Is Google just playing games with me and will this account be banned soon?
I doubt they are playing games with you, they are just oblivious of the fact that its you again. If you are using a new name and such then there should be no reason why two people in the same house can each have an adsense account. I would be cautious with this as you could be banned any moment if they do actually trace back to you, just stick with the same ip and such.
I'll keep everyone updated on what happens. So far so good, I've had the ads on my site the past few hours.
That's fine if the address is same but different user name. As long as you are not against any adsense TOS and not repeating what happen previously, then your adsense account will be safe
