Its interesting to see how both sides of the issue are related and be so

It is not uncommon for someone to turn off a block of addresses when there
is a serious problem. Things like ping floods or denial of service attacks
can prompt this type of action. Actions that involve any type of service
disruption including attempts as accessing a system can also prompt
filtering out networks. Some systems can turn on and off filtering based
on time delays and pre programmed parameters based on the type of problem.

Your right sometimes it is next to impossible to find the root of the
problem but on the internet you have to come from point A to point B and
someone somewhere is logging at least some of this activity. The hard part
knowing who and what and hoping the person logging the data keeps it
around long enough for you to find it and use it. 

Good Luck with your game!
