in general terms, yes, of course
why?
because this game not allow level harrass, it split players by levels in ranged groups, so you ever will compete against players with likely level than you...
then, what make u more weak or strong than rivals?
TIME training, yourself, your hoes and your actresses... and that means that to level up fast is negative to your profit here.
Btw, if you only want to play some fun time, and no matter if you dont win any trophie, and get shame and hospital every time u can... well, then u can level up fast without any problem ;)
