Personally, I don't get why Twitter is still popular and that a lot of casino really use it. It is full with bots and I really doubt if it is really so effective for marketing.
There are bots but at the same time real community as well so most of the promotions are done there.Moreover you will find the gambling community is active there while most of the other social platforms are not good and suitable for such promotions.They are getting attention from Twitter so it's going good for them.
To be honest, I just found out that there is a bot working to claim bonus gift codes, whereas maybe if it's true that bots exist, I want to know how the bot looks like and how it works, until now I still think logically that it's just hand speed and only people are quick to claim it's not like a bot says it is.
But if it is possible that there are bots, I think it is necessary to find another platform to distribute the prize code in other places such as discord or telegram so as to provide an opportunity for others to claim it and get prizes from Duelbits. social media is too open and crowded with users so it's hard to fight over it.
