Tipico web-site is offered in various different languages, as well. It means they slowly target audience outside Germany.
If they has so "badly" reputation amongst German affiliates - I'm curious, how they want to attract affiliates from other non-German speaking countries? Perhaps they make enough money from German market and they just do not care about other markets.

It's really funny!. They really do not care about some nations. Tipico (when listing languages supported) , list "Nederlands" language under Belgium Tab. That's not nice news for pure Dutch people living in the Nederlands. Maybe they do not target Dutch market.
