Optionally add requests to external safe browsing lists (detect malicious / SPAM-URLs)

[sypets]

This is more of an optional feature but it would be really nice to have this and also consider possibly using several check methods, some of which might be external for specific links types (e.g. external URLs, email-addresses).

Possible sources:

• Google Safe Browsing Lookup API: https://developers.google.com/safe-browsing/v4/lookup-api

Safe Browsing is a Google service that lets client applications check URLs against Google's constantly updated lists of unsafe web resources. Examples of unsafe web resources are social engineering sites (phishing and deceptive sites) and sites that host malware or unwanted software. Come see what's possible.

The HTTP POST request can include up to 500 URLs. The URLs must be valid (see RFC 2396) but they do not need to be canonicalized or encoded.

⚠️

Clients using the Update API are required to set up a local database and to perform an initial download of the Safe Browsing lists they want to work with.
