Which scene tracker's torrents have long life?

# In your opinion, which scene tracker(s) has the torrents seeded for long? I know most of you will come up with sct or ftn, but i want to know those less popular (which i say, under rated) trackers where i can find older scene releases.

# For older porn scene (in rars) which is the best?

Please don't spam around saying "Nothing to think more -sct and TL " I do agree but it doesn't mean there aren't others.

One i found is digdogdug which has very old scene i missed months ago.

Since someday Rtt, created a new section "request" I suppose there'is some old stuff from the scene.
About pr0n, you can find old thing on puretna and empornium.
