Add nominations for user blocks to the list below, but please do so only after reviewing Wikivoyage:How to handle unwanted edits. After a nomination has been made, the nominator is responsible for ensuring that appropriate notice is given on the allegedly delinquent user's talk page of the nomination made here.
In general the preferred way of handling problem users is through the use of soft security. In the case of automated spam attacks the spam blacklist can also be a valuable tool for stopping unwanted edits.
For an archive of older nominations, see Wikivoyage:User ban nominations/Archive. Nominations are automatically closed and archived after 14 days of inactivity.
