A brief line from this comment indicates that the author of the cryonics-critical comment quoted here was perhaps not the one that deleted it.
You know what - I am rather glad my comment was deleted on less wrong - good reason for people not to post on there.
Was it deleted by a moderator?
Honestly, the decisive downvoting seemed to do the trick of hiding it from casual readers who don't want to see the long annoying rants. I don't think it was casting any doubt on the credibility of cryonics.
While it sounds like the author regrets posting it, I would think they should be allowed to delete it themselves.
Edit: Originally titled "Cryonics critical comment deleted?"
Richie may be a troll, but there are those who seem to take him seriously and applaud his efforts. He doesn't seem to be a deliberate troll, just an over-emotional jerk who is genuinely upset about cryonics. I realize we need to have a filter in place to keep the SNR good, but I thought the karma system was probably sufficient in this case. I could be wrong though; I don't have any experience with moderating a forum personally.
The fact that Melody Maxim takes Richie seriously changes my opinion of her a lot more than it does of him.
