I'm not sure where you obtained that information. There are active people on Twitter. I have been using the platform since 2016, although I am now exploring other options since Twitter has been poor for me due to the decreased traffic from hashtags.
Despite this, I still receive engagement and gain followers for my tweets. However, converting followers within a safe-for-work (sfw) niche has proven to be extremely challenging, especially compared to my previous experience in monetizing adult content, which was much easier.
Although I will continue to experiment with new ideas on Twitter occasionally, my primary focus now lies on new projects. Twitter has been increasingly irritating, and I have run out of fresh concepts.
Furthermore, acquiring followers is not any different than before for me, as I have been using a custom bot that I developed myself for years. If you are facing bans, it is likely due to overly aggressive settings.
