* `grow_factor` - the multiplicator applied for the subsequent symbols inserting by the follwing rule:
- score = score + grow_factor * symbol_weight
- grow_factor = grow_factor * grow_factor

by default this value is `1.0` meaning that no weight growing is defined. By increasing this value you
increase the efficient score of messages with multiple `spam` rules matched. This value
