To our American friends, the First Amendment does not apply outside of the USA, and even if it did, it would not be applicable. The First Amendment is to stop the US government from creating any law prohibiting any form of peacable or religious speech. The law applies to the government, it does not apply to public or private companies nor does it apply to individuals. The actual text is: Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.

SORBS has a right, and an obligation, to publish truthful information. SORBS strives to ensure all the information is accurate and will correct any errors as soon as possible after being notified of errors. Listings that are truthful, that are old or not be current, are not errors. This means if an IP is listed as previously sending spam, the fact it does not currently send spam does not imply the listing is an error.
