Gamers are among the savviest users. Many have bright coding skiils and deep knowledge on how things work. That is a good customer base to deal with. On the other hand many tend to remain "invisible".
The fact a small portion go through associateLead and even visited web page is a potential symptom they have JavaScript disabled and/or resourcing to very smart proxy servers, often used to access peer-to-peer networks (P2P).
That is a challenge for Marketo and most applications interacting with prospects and customers.
One suggestion is trying to reverse the IP of randomly selected leads.
geoiptool.com is a good one. Some may be in genuinely unusual locations. The remaining would be behind proxy networks such as
Tor. Identifying 85% or so is an interesting challenge. I am happy to join the cat and mouse game
