Every single tracker displays how many seeders/peers each torrent have, but not ABB. Why?

Imagine being able to sort search results by seeders count. Or getting a table of top 200 audiobooks. Or finding valuable torrents which are on the verge of dying and supporting them.

In source of “Recent audiobooks” HTML page there’s a trace of hidden “Seeds” column, maybe some time before it was possible to see these counts.

Are there any other way to get this data?

I’ve seen a torrent tracker which mirrors all torrents from ABB (adds them to its own catalog), seeds counts have been available for these torrents, but I don’t remember what was this tracker, also it wasn’t possible to find all torrents by source (ABB in this case).

EDIT: Probably I was talking about 1337x tracker, it does have some overlapping content with ABB, but it doesn’t mirror everything. There’s a table of all audiobooks which can be sorted by seeds, but you can’t search through this category only.
