Though, ad credits were done on IP 12.345.67.98, they were sent by 12.345.67.89. Which then leads me to believe they were done at a neighbor's house or similar, and then she or someone in her household, logged on her IP, then sent herself the ad credits. Either way, the ad credits were sent by IP 12.345.67.89.

Sent to mystral21 by IP: 12.345.67.89.
So from the looks of it, it is frauding. And there's more than just these accounts that I've listed here. This is why I said, none of the IPs should ever cross one another. The story that you have given, does not really match that of what went on, because all these ad credits, went direct to mystral21, rather than going to someone else, and were sent via that 12.345.67.89 IP.
You cannot get banned simply by not knowing where they came from, however, as I stated previously in other posts, you are responsible for your IP, so if someone in your house hold frauds, you have frauded as well. I hope that answers your question(s)
