It goes both ways, if you have been active some time back and stopped playing there, I am sure stake.com will take notice and try to onboard you again with such wagering bonuses. Actually IMO these wagering bonuses are specifically crafted for such inactive players. Stake.com is an ultra-modern casino and if any casino has the capability of leveraging such bonuses, it's stake.com and I am sure stake.com is doing that.
For active players, they don't need to give them an extra bonus as they are already wagering and losing lol, so for them, regular no-wagering bonuses are enough.
