I am a little confused about the using the trackers. If this is made public, then participants should know this before the begin. You're exact location will be wide open on the WWW. Unless we are only going to dox them if they keep the package too long, which we aren't sure how long is too long yet. But, if the participant doesn't mail the package, unless someone is willing to drive over and beat them senseless, what good is knowing the location? I mean, has anyone sent a fake tracking number after "they say" that the package was mailed... only to be lying? I'm confused as to how that works.
If we send it to someone who drops off the forums, we know their address and name and can dox them anyways.
