Arrowverse Wiki has a number of policies and guidelines that its users are expected to follow.
Should a user break a policy three times, they'll be banned for an amount of time, depending on the offence. Alternatively, a user will be blocked regardless of how many warnings they've received if they've repeatedly broken the policies to a large extent. Once a user's block has been lifted, if they repeat the exercise and break the same policy again, they'll be warned only once, then blocked.
