Didn't know if the new Ricochet system, with kernel level access, had other potential more evolved than at the time of the OP. For now, I bide my time I guess. It's a price to pay for limiting cheaters I guess.
PS... you all are great at follow-up and response. Thank you for great customer service.
I would reiterate what I said before, no one has been banned using our router, nor could they detect that you're using the Geo-Filter, to them it just looks like your unable to connect to some servers, people will have that regardless of the router they're using - they can't ban everyone who can't connect to a server. More than likely what has happened is you've encountered players who were so annoyed you killed them that they reported you and the system auto bans after a set amount of reports and once it gets in front of a person to look at you'd be unbanned, as was likely the case for the original poster.
