Blocklist checker

Search one IP address, email address, username, URL or domain at a time.

A match in our database, or no match, does not by itself mean something is spam, abusive, or safe. The full Forum Fortress plugin weighs many signals together when making decisions.

Each value is checked independently. Results do not indicate that any of the submitted values have previously appeared together or are associated with one another.
