Translations:Test Wiki:Blocks and bans/3/en
Blocks are technical measures, and they are placed either to prevent disruption, or for testing. Blocks placed to prevent disruption are usually placed by one of two groups: Bureaucrats or Stewards. They are most often placed due to disruptive editing such as, but not limited to, vandalism or spamming. However, blocks to prevent obvious and ongoing or imminent disruption may be placed by any Administrator. Blocks can be made for testing purposes by any Administrator, and are most often placed on an alternate account or another person. Blocks placed on another person for testing should last up to two hours. Blocks are also made by the AbuseFilter extension for actions matching certain filters. It is not advisable to revert blocks that are marked as suppressor/oversight blocks without the consent of a suppressor, nor to revert steward actions without the consent of a Steward.
