I don’t think that Rollbit team will just award the winner’s without due checks, because once they scrutinise the accounts tweets then they’ll be able to check whether it’s an legit account, or an account made just for participating in the giveaway’s. @aysg76 that’s a fine strategy too because then the end result is in your hands, but for those who’re just starting out or have less funds these giveaways are a good way to engage with the casino hence Rollbit should continue them.
They don't have time to scrutinize these twitter accounts to check the bot activity and they are willing to giveaway to these random users and you would see them in most of the casinos and not too much worried about the issue and happy to focus on gameplay and enjoying there only.
Honestly, it is not that much of a big trouble to check if an account is a bot or not. I know twitter literally declined to disclose the number of bots on their website, even if it meant tens of billions of dollars on their pockets, but the reality is that we could do that with just a few simple steps.
First of all, there are websites that tell you if an account is a bot or not, you literally type in the profile name and they will tell you if it is a bot one or not.
Secondly, you pick winners, check every single name there, if you see bots remove them, add in the reserves, see if there are any there, and keep repeating that until you have winner list without a bot. I have done this over a dozen times so far, takes about 2-3 hours max.
