>>19757>Is it the case that it doesn't list seeders/leechers?No it doesn't. You might know it's a DHT crawler, that stores the metadata from the network.
>How well maintained are most magnet-link results?For most content you get a dozen results. GOG games usually have torrents for each of the last few minor versions.
The site adds a date to each result. Contrary to expectations, older torrents are often still seeded in contrast to slightly younger ones.
Searches can be a bit crude when compared to curated indexes. Some music results are clogged by popular compilations. In this case you should add discography or an obscure release by the artist/group.
