Put the robots.txt rule in the file at the root of every domain and subdomain, for example https://example.com/robots.txt. The token SnapchatAds is matched case-insensitively. robots.txt alone may not stop SnapchatAds, so add the Nginx, Apache or Cloudflare rule as well.
robots.txt: block

Disallow: /robots.txt: allow
# Allow SnapchatAds

# Nginx: return 403 to SnapchatAds
if ($http_user_agent ~* "(SnapchatAds)") {
return 403;
}Apache
# Apache .htaccess: return 403 to SnapchatAds
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} (SnapchatAds) [NC]
