I was asked to respond here.
After reading most of the topic, including FortuneJack's response about their Terms, I won't Support the Flag that claims they "violated a casual or implied agreement".
I do think the Terms are shitty though. If certain bets are not allowed, cancel them before the match.
Not all the duplicated bets are canceled, only the ones that exceed 100,000 in euros.
You should clarify this in your Terms and Conditions.
