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.
On Twitter, news, tweets can be spread out very quickly. It can cause massive marketing effects that is one of reasons casinos very like Twitter in their marketing strategy.
Bots are popular on many social media platforms and those platforms are even not strictly against bots as they want to make their platforms as most crowded as possible. Sometimes, they step in like Facebook, Twitter to get rid of bots and farm accounts but after each wave of such clean-up, things will be back to normal for bot activities.
Under Elon Musk, business accounts will have to pay very expensive cost monthly only to maintain their Yellow badges. That's crazy.
