Remove all accounts from a given DOMAIN without leaving behind any
records. Unlike a suspension, if the DOMAIN still exists in the wild,
it means the accounts could return if they are resolved again.
When the --limited-federation-mode option is given, instead of purging accounts
from a single domain, all accounts from domains that have not been explicitly allowed
are removed from the database.

desc 'crawl [START]', 'Crawl all known peers, optionally beginning at START'
long_desc <<-LONG_DESC
Crawl the fediverse by using the Mastodon REST API endpoints that expose
all known peers, and collect statistics from those peers, as long as those
peers support those API endpoints. When no START is given, the command uses
this server's own database of known peers to seed the crawl.
The --concurrency (-c) option controls the number of threads performing HTTP
requests at the same time. More threads means the crawl may complete faster.
The --format (-f) option controls how the data is displayed at the end. By
default (`summary`), a summary of the statistics is returned. The other options
are `domains`, which returns a newline-delimited list of all discovered peers,
and `json`, which dumps all the aggregated data raw.
The --exclude-suspended (-x) option means that domains that are suspended
instance-wide do not appear in the output and are not included in summaries.
This also excludes subdomains of any of those domains.
