The previous 'restored' email contacto@posidonia.eivissaenvironmentalwatch.es was never a real mailbox — the project has no persona jurídica behind it. This is a CORRECTION, not a privacy regression: the user's actual contact is their personal Gmail. Also: - Finalized robots.txt with Allow / + Sitemap - Cleaned up the README TODO placeholder about the email - Updated CHANGELOG with 0.5.2 entry documenting this change The visible link text 'Itziar ZG' is unchanged in both files.
