Hi @catuyen,
Any users blocked for the time specified in Wordfence > All Options > Rate Limiting > How long is an IP address blocked when it breaks a rule or Wordfence > All Options > Brute Force > Amount of time a user is locked out will disappear from your Blocking page once they’ve lapsed. Manual Live Traffic blocks are also subject to this rather than being permanent by default. You can choose to increase this time to days so you can catch them on your Blocking page – where you can then to make the blocks permanent or copy/paste them into Cloudflare’s firewall. However, we generally find that a manual blocking strategy is ineffective and Wordfence can do all of the important blocking for you when it’s required.
IPs can be reassigned over time to different users/servers, so manually maintaining this yourself isn’t generally recommended. Wordfence keeps a list of malicious IPs and common sources of attacks that we’re seeing across our customer-base.
Thanks,
Peter.
