Yup it will most probably get spam, *however* I don't think that the
server will give out blocks in most cases, as the email is supposed to
numblocks = <num>
blocksize = <28-31>
in it to say how many blocks / what size blocks you want, now I doubt that
most spam has that in it.. more like 'Get Free Live Video Sex for $9999'
(Yes I know that is a contradiction, but believe me, I have had a spam
So, hopefully spam wont bother it, other than, of course, wasting
Someone could deliberately force it to send 10000000s of blocks out, which
never get checked, but they can do the same with the normal method..

You answered it yourself, although, actually the blocks are re-sent each
2^56 key SUBSPACE of the 2^64 key keyspace, so we have actually re-sent
blocks from some subspaces already (I think 0x64 is being re-sent now).
Don't worry, the keys wont go missing.. it just might take us a month
or so to process that exact key, but we will still process other keys
in the meantime, so it wouldn't make any difference....
