Couldn't hurt. A lot of their rules are stupid, and I think big network violations suck. Its stupid, cause my friend has given me tons of cyber cash and resources and I can't give him anything back because most of the time I check my nation at school.
Okay, just checking it out. I noticed and I have never in my 2 years playing seen an "inter team" foreign aid deal get flagged for cheating. In recent time, they've really started cracking down on that, so watch. My friend and I use the same network at the college we go to and have not been able to send FA to each other. Same school kind of screws things up. I'd talk to the admins though and explain that you found the flag so they know what's going on and that you're not cheating.
