By-passing tracker?
I created a tracker to collect additional information as part of registration. It appears to work when I try it from several machines and browsers, but - I still get loads of registrations (presumably from bots or operator farms) which simply do not include the tracker (ie register as if it wasn't there at all) - ?
Any idea how they manage to by-pass the tracker, and how I can stop this?
