Well I've never had the (dis?)pleasure of playing DipperDon, but I've never been blacklisted, nor have I blacklisted someone. If I ever blacklist someone, I don't think I'll tell them. I think I'll just quietly foil all their plans in any games we happen to meet. That would give me more satisfaction. >=D
My most emotionally traumatic experience with another player was also in my favourite game ever and the anger and tension definitely added an interesting dynamic to the game. I was quick to forgive, though I had suspicions the other player was not as quick, but we eventually reconciled over our mutual defence of WTA over PPSC. I wish he still played here.
Regarding kamikaze's, I don't condemn them, but I certainly don't condone it. I've never kamikaze'd, nor have I threatened to. I have been kamikaze'd against, but it was ultimately futile, so I didn't really feel that bad about it. I think there are more subtle and more effective means to achieving revenge if you're into that, and I'm more of the school of turtling when stabbed. I always give kudos if I think I've been very well and jolly stabbed and I think it's more effective to stay in the game as long as possible and see if the diplomatic climate changes. I've eked a couple draws doing this. That said, habitual kamikaze is just a stupid strategy... the only reason I would ever kamikaze is to avoid being predictable.
As a mod, I feel I should say that discussion of why DipperDon has been blacklisted so much should be left to private conversation between DipperDon and the blacklisters. I have a feeling that the reason is quite different in the mind of DD and the blacklisters and that it can't end productively. You *can* carry on if you want, but I wouldn't recommend it.
