I just looked at that node you provided, I must say it looks like my code :) I rarely ever post as anonymous and I don't remember making it, but it was probably mine.

I know this isn't going to always work and if it does, the data won't be reliable. This is just to be a fun little script to try to make an attempt to figure out where my traffic is coming from.

I am almost possitive there is a logic error, like someone said above. I'll take a quicker glance to see if I can figure it out, thanks for your help everyone!
