Posting rules, in plain words
Self-promotion is judged case by case.
- No Self-Promotion Without Context: Share your work openly, but avoid posting solely for self-promotion. Instead, focus on sharing progress, lessons learned, and asking for feedback.
- No Spam: Spamming links, irrelevant content, or unsolicited advertisements will lead to immediate removal. Keep the focus on building and learning together.
- Transparency in Tools & Resources: If you share tools or resources, be transparent if they’re paid, free, or affiliate-linked. This helps maintain trust and clarity in the community.
Quoted from the community’s own published rules. Always re-read them before posting.
