It doesn't matter if you're using Mullvad's VPN and a proper browser, you'll
still get blocked for specific searches [1] with a 403 or 429 HTTP status code.
Mullvad only blocks the search request and doesn't prevent you from doing more
searches.
The logic should handle the blocked requests (403, 429), but not put the engine
on a cooldown.
