Someone who has bot net still can spam

[dannotestein]

And I also have a question. If someone use great hash power to mine his ID and get a large reputation point, if it means that even that ID is deprecated (owner departed) , the ID will not be put into recycle for reuse for others, for a quite long time?

IDs expired after one year unless re-mined.

Each ID has limited search space which limits potential mining power per ID over time.

Someone who has a bunch of hash power still can pass ordinary people's spam reputation point threshold. And people can't put the threshold too high, otherwise they will miss the ordinary people's mail.

Don't you think that's a problem?
