Yes and no.  If I add something to the manual blacklist,
it gets listed within a few minutes if it wasn't already.
It doesn't change any report counts; it forces any new
records onto sc.

An accelerator list would perhaps lower thresholds,
increase hit counts, etc.  This is a simple "or"-type
blacklist.

Yes.

Correct, but there are other rare errors in SpamCop, such as
when URIs or domains don't get extracted properly, usually
due to obfuscation.  If I see that happening with my personal
SpamCop reports, and I'm sure the message is a spam, then I
add the domain to the manual blacklist.  Usually I try to
mention the lack of detection to the SpamCop deputies also.
I hope others do similarly.

It's mainly meant to address too few reports, slow reporting,
or processing errors.

P.S. I hope everyone is reporting fresh spams to SpamCop.
