Hello Andreas
My last deposit was on September 3 with the promo code WILDSALE. Then I won some money and withdrew the whole balance on September 21.
I'm not registered in the freeroll (despite having earned 128 SPs from 888 in September), perhaps because I net withdrew during the promo period or because I used a code when depositing.
I think I'm not labelled as a bonus abuser because I got another Wildsale offer last weekend (and declined it).
