Well, most communities don't allow asking for support through individual posts. In this case, if you keep making such posts, you will eventually be banned for life by Reddit. Some communities conduct weekly threads where you can ask for support, but your comment mostly gets lost in the huge number of responses. Personally, Reddit hasn't been of much help.
Reddit communities can be incredibly helpful for launching a product, as you can tap into a diverse range of perspectives and expertise. Some great communities to join for support on your Product Hunt launch include r/ProductLaunch, r/Entrepreneur, and r/Startups. These communities are filled with valuable insights and feedback that can help you navigate the complexities of a launch successfully.
