PrimeDice is a source of inspiration. I wonder why they dont respond to this issue

Im pretty sure they do, no official confirmation yet from Stunna or Micro regarding this . Probably they are checking on things regarding this or perhaps they KYC submitted isnt clear enough to convince them
only thing limiting your number of bets is maybe your own limit to bet speed.
Im pretty sure there are some limit for the roll per minutes otherwise someone could create a script and run it on full speed and clutter all their database. I cant really recall about this policy
