// description: |-
// Comma-separated list of filters to apply to results. Recognized values are:
// 'open' -- include peers that are not suspended or silenced
// 'suspended' -- include peers that have been suspended.
// If filter is 'open', only instances that haven't been suspended or silenced will be returned.
// If filter is 'suspended', only suspended instances will be shown.
// If filter is 'open,suspended', then all known instances will be returned.
// If filter is an empty string or not set, then 'open' will be assumed as the default.
// in: query
// required: false
//
// responses:
// '200':
// description: |-
// If no filter parameter is provided, or filter is empty, then a legacy,
// Mastodon-API compatible response will be returned. This will consist of
// just a 'flat' array of strings like `["example.com", "example.org"]`.
//
// If a filter parameter is provided, then an array of objects with at least
// a `domain` key set on each object will be returned.
//
// Domains that are silenced or suspended will also have a key
// 'suspended_at' or 'silenced_at' that contains an iso8601 date string.
// If one of these keys is not present on the domain object, it is open.
// Suspended instances may in some cases be obfuscated, which means they
// will have some letters replaced by '*' to make it more difficult for
// bad actors to target instances with harassment.
//
// Whether a flat response or a more detailed response is returned, domains
// will be sorted alphabetically by hostname.
