I joined bunch of Duelbits contest and trivia on twitter. It’s almost impossible to win due to the bot accounts infesting the comment section to increase their chance of winning. I’d rather focus on casino website promotion than the social media that saturated with bot account.
I won't say impossible but yes the bot accounts have made it hard for us to win in them as there are hundreds of them ready to participate in such contests and giveaways.The chance are high for us when there's some real participation and some requirements which they can't qualify for.But still we can try it to see our luck.
Sadly this in an ongoing problem that is very hard to stop or to fully solve. I know it doesn't take a long time to participate in these contests on social media and I have seen some members here winning or been able to claim some codes they drop, but I never really tend to get lucky and get frustated all the time with abusers/bots. That is also why I don't really chat in any gambling site due to many abusers trying to catch some rain.
Actually it can be minimized as said above by having requirement(s) in order to be eligible for the giveaways. Of course there is also at least one consequence of having requirement especially if the main purpose of the giveaway is to attract new users. If the requirement is something like minimum wager, so it wont be attractive for new players because they will not be able to claim it. In my opinion, the best way is that duelbits provide 2 different giveaways. First is for active players with a specific minimum wager and the 2nd one is for new players or even for anyone who create the account after duelbits post the giveaway.
