Defendr keeps a network list of accounts that spread phishing links, harmful files or takeover attempts across servers. Entries of its own need evidence and two reviewers. It also takes over the entries of the ScammerAlert community lists automatically, without checking them, and marks them as such. Right now every listing is a hint only: your moderators see a neutral note in the log, and nothing happens automatically. On the Global network page you decide whether your server uses reviewed listings and whether it sees ScammerAlert hints.
