I went down this path too thinking there’d be one solid “group,” but it’s more spread out than that.
Reddit itself is actually a good start if you use it right. Subs like r/socialmedia, r/InstagramMarketing, r/TikTokhelp, r/Entrepreneur tend to have people sharing real experiences, not just theory. The key is reading what performs well and what gets downvoted, you learn platform norms pretty quickly that way.
For more focused discussions, Discord communities can be useful, especially ones around creators or niche industries. They’re more active day-to-day, but quality varies a lot.
What helped me most wasn’t just joining groups, but posting, getting feedback, and adjusting. You pick up way more from real interaction than just lurking.
Also, following platform guidelines directly (Instagram/TikTok docs) is underrated. Most bans happen from small repeated mistakes, not one big violation.
