Every submitted site enters manual review before it can send collaboration requests, with reporting and moderation available after approval. Founder profiles connect sites to the operators behind them; moderators can suspend abusive or misleading accounts.
Domain verification, manual review, and scoring across Moz DA, Ahrefs DR, Majestic TF, spam score, traffic, WHOIS, IP, and geographic signals. Website ownership is verified with a meta tag; private contact details remain hidden until the workflow reaches completion.
Takeaway: Backlink Exchange publishes the broader metric and geographic scoring stack; Indie Chains makes founder context, moderation, reports, and completed-collaboration reputation more visible.
