Consider talking to Pinner

[MSevey]

It's sometimes possible for nginx to fail to call accounts on upload. See https://discord.com/channels/542938080349519882/542939142183452672/989840713028096030. This means that we're allowing the upload of skyfiles that are not scanned by malware-scanner and won't be blocked if they contain malware.

On the other hand we have Pinner who's running daily sweeps of what's actually being pinned by skyd on all servers. If we allow Pinner to expose a list of all skylinks (limited by timestamp, counts, etc.) then it might be useful to have malware-scanner fetch that list incrementally and add any new skylinks it encounters to its scan queue.

This is just an idea at this point and the only immediate action item is to have a chat about it.
