You may be heard about being gubbed or some similar word. Being Gubbed means that they found your activity suspicious, because you played only promotions and nothing else, so they banned you from gaming, betting or both. Gubbing is usually for ever, and in order to avoid this you may need to know few suggestions:
-if you play a promotion regularly, let's say play 25 to get 10 weekly, you may want to deposit 26 or 27, and after you completed to play another 1 or 2 pounds.
-if you play a gaming promotion regularly, you may want to do some few extra spins, or to do couple of spins after on another game (if you have play 30 spins on Vampire to get 15 free spin, play 31 spins and then play 2 spins on roulette).
-your profits will be a bit lower, but you will have a cow to milk for long time, instead of gaining few extra bucks and be gubbed in few weeks.
Good luck
