though if you think that the twitter contests main goal is to attract engagement (farm) then the bots aren't such a big deal, unless they start undermine credibility on the company too much
Partially they can check Twitter farm accounts and verify their quality by audit scores. These sites are not perfect but a company can use it as part of their toolkit to reject low quality accounts and increase effects from their marketing campaigns.
https://twitteraudit.com/https://www.followeraudit.com/this tool will help the site improving their giveaways . so anything that will make them find abusers is literally a big help.
and also maybe extending other giveaways not only in twitter like at least telegram or facebook (sorry if I missed something that already running)
I am willing to bring more support to those initiative .
Oh, this issue is still underway. I think Duelbits should stop the promotional activity on "Twitter" and reconsider promoting the same on let us say Telegram. That seems to be very reasonable and I am already seeing various other casinos making good progress on that front. I never saw any complaints from that end. Even Instagram is good for that matter. I don't what makes Twitter so complicated or easy to manipulate but its algorithm is something that has been playing devil all the time. (all the bots and stuff).
Duelbits Instagram already has 32K followers which means its active too. However, no promo codes has been published so far as we can see.
I am not sure if Duelbits has thought about it already or not, but that's the easiest one.
