A blocklist and a passlist can be configured in /etc/searxng/limiter.toml::

    [botdetection.ip_lists]
    pass_ip = [
      '51.15.252.168',  # IPv4 of check.searx.space
    ]

    block_ip = [
      '93.184.216.34',  # IPv4 of example.org

b8c7c2c9aa [mod] botdetection - improve ip_limit and link_token methods
- counting requests in LONG_WINDOW and BURST_WINDOW is not needed when the
  request is validated by the link_token method [1]

- renew a ping-key on validation [2], this is needed for infinite scrolling,
  where no new token (CSS) is loaded. / this does not fix the BURST_MAX issue in
  the vanilla limiter

- normalize the counter names of the ip_limit method to 'ip_limit.*'

- just integrate the ip_limit method straight forward in the limiter plugin /
  non intermediate code --> ip_limit now returns None or a werkzeug.Response
  object that can be passed by the plugin to the flask application / non
  intermediate code that returns a tuple
