There are some sponsors, like
Sex Money, who are based in Europe, specialize in European traffic and automatically detect browser language on their paysites and display the paysite in the surfers language where available. That way you're not redirecting anyone, and a Non-US LL or TGP owner will still end up at the sponsor they clicked on if they're checking, just in their own language. They also have some billing options that are particular to EU traffic, so you have a better chance of converting that traffic. If you've got a ton of this type of traffic you may want to consider either them or a sponsor like them.
In any case, it's a decision you need to make on your own based on YOUR traffic, and I agree that you DEFINITELY do not want to redirect surfers directly off of galleries or free sites. That will get you banned in a heartbeat.
