You should not be returning a brush to its stand dripping wet. It should be shaken until it does not fling any water droplets, then gently brushed on a towel before placing into a stand to air-dry.
My higher quality brushes come with maintenance notes. Interestingly, they all state that on no account should the knot be wrung dry by hand, yet I see many so-called online experts doing this.
I have consolidated the various OEM instructions into a regime that I use for my brushes:
* After shaving, rinse brush thoroughly, ensuring all soap is removed.
* If water is hard, I soak brush for 10 sec in soft water.
* Shake brush in a linear flinging action to de-water. I do this by aiming the brush fling into the shower recess, and I nominally do this 20 times.
* Gently stroke the brush 2-3 times North-South, then East-West on a clean dry towel.
* Place brush in stand (inverted) to air dry.
* To expedite drying, I place the brush in a location where it receives constant air flow.
About every six months, I clean and condition my brushes by soaking in a warm dilute solution of borax, vinegar and detergent. The brushes are then rinsed thoroughly, air dried, and put back in circulation. Some recommend the use of hair conditioner after the cleaning process, but I do not subscribe to this step, nor is it recommended in my OEM instructions.
