Trust me it is not possible to get registrations or even traffic on your forums through facebook or tiktok that are bombard with visual content. However, in my experience site slike Bluesky, Threads or even Twitter can be useful as these sites are less visual and more text based.I still believe that making use of social media platforms when it comes to growing a small community is always very effective if you know how to target the right audience on the different social media platform you are promoting your community digitally. Facebook and TikTok still remains among the most effective social media platforms where you can promote your community digitally.
