What are the silver Fluther awards for?

http://www.fluther.com/awards
The silver ones are
– Pilgrim: I’d tell you, but the CIA will [REDACTED].
– Old-timer: If I told you, I’d have to kill you.
– Robot Crush: These aren’t the droids you’re looking for…
– Perfecto-fish: We’d tell you, but our standards are impossibly high.
– Cake in the Frizzer: It’s going to be tough to find everything in this secret volcano lair.
-Feeding Frenzy: Do you think you’ll live to tell the tale?

I don’t know if fluther mods let you post what you get them for publicly, but if anyone could PM me or something?
I’m really curious (also just noticed I have been awarded Feeding Frenzy.. don’t even know what I did for it??)
