I didn't take part in any of these games but it doesn't matter actually as I'd just like to say what I think about this.
Generally, I agree with Ich. Hosting is a big responsibility and this responsibility is normally based on pure enthusiasm so it's a bit rude, IMO, to blame someone for not foretelling the disaster and thus not backuping all games on local computer.
I hosted PBEM dom games several times and I may say that it is very unpleasant when someone starts annoyingly blame you if anything accidentally goes a bit wrong. However, I always found the means to deal with such people).
Also I think that you shouldn't mix up disaster with laziness or something. If the host just suddenly disappears with no callback when you know for sure that he is fine and visits forums from time to time than this is irresponsibility and impoliteness. I can say no good about such people (I met such things several times). But this has nothing to do with the case when a host (probably) just made a (not obvious) mistake. This should be understood and forgiven.
