It has been stated multiple times before, Traders are exempt form the 4 hour system rule, as in they can keep coming back to a system. Given they are trading they shouldn't be engaging pirates in the first place, the pirate fres the CD or disrupts the lanes, he's the one re-engaging, which is fine per the rules, as he's the victor in the last engagement. The trader gets pirated/destroyed again. He tries again with the same result. He can keep doing it all day the only thing he accomplishes is bankrupting himself at the end of the day.
Saint Del is considered a holy healer of diseases of children, but also as a protector of cattle.
