This is true, and Blocks suffers from all these classical problems :(

Possibly Michaels WoT idea might help eleviate some of these issues,
but in the meantime here are some other ideas (off the top of my
head... asbestos underpants are on :-) ...

1) Password lock servers/blocknets... so only 'authorised' people
   can join. This would allow private blocknets which is probably
   desirable anyway, but without WoT I cant see how it can be
   applied to the general anonymous blocknet.

2) Staticstical analysis can detect extreme flooding, but wont
   really help stop short burst flooders or slow flooding.

3) Spammers sending bogus ads are a real pain. Without strong
   authentication there is no way you can trust an advert.
   Explicitly checking the validity of the underlying file
   is infeasible (if not impossible). The only thing I can
   think of that might be appropriate here is some form
   of phyical violence... I wonder if there is a POSIX call
   to send an EM bust through the console like they always
   so in Startrek. I could equip block servers with a DDOS
   autotargetting facility, but that would get misused as
   well... still we can dream ;-)

Hmm... looking back at what Ive just written there doesnt
seem to be much content there :( But, hopefully, Michael
will have more to say on the WoT idea sometime soon.
