I am not sure what is considered to be excessive tipping at Bitsler,there should not be any limits,unless the faucet is being abused
there must be some sort of an automatic script that decides when and why a user is blocked
I highly doubt admins or support would sit and go through all of the tips to determine if the tipping was "excessive" or not
at another top dice site,for example,there is a special script that allows mods to catch people who create two and more accounts and tip them in circles only claiming faucets
