Recently the SubsPlease batches seem to have been added to the skipping policy, unless they count as duplicates?
It would be a good idea to at least keep fetching the smaller ones like 480p (that should easily be under 8GB), as SP has been trying to do batches with fixed subs where possible and these might not be available from other releasers, it's less about the release itself, and that animetosho extracts the subs and archives them, so for people that already have the releases and just want updated subs, it would be really useful.
Updates subs are because CR has been doing SRT-tier subs first and then later updating with properly typeset versions, this mostly applies to subs this season, but at times they've done updates to older season subs.
So if admin can at least fetch the small ones, that would be great.

No, both platforms are fetched. Some appear on both platforms, while others are exclusive to only one.

So torrents are only available nyaa. No tokyotosho?
