is the poll is still allowed to add more website since you forgot to add CyberDice, YOLOdice and MintDice. also, Nitrogensports and onehash also has a dice game on their platform.
I'm not sure what factor to considered why OP didn't put more dice sites and i think i do agree for you he should be added more options to vote because some people maybe want to vote for dice sites you mentioned above but so far Cyberdice and onehash are associated and not necessary to added both of them so just pick between them is good i think however i had just submit my vote today
