Oh man, Pilsu is such a stud. I wish I had the [FEMALE] tag so I could have his babies.
I concur. This is the best idea ever.

Really, I can already edit an old post to contain nothing but an ASCII bunny, how is that any less context-removing than outright deletion?
I don't really see edits feeding much in the way of drama. The post saying it's been edited hardly proves that he really called you a cockweasel instead of the honeymuffin it says now. I think calling attention to meaningful edits should be more of a priority than making already rule-breaching bickering a bit less efficient.
You can remove the contents of your post, but you can't destroy the evidence that you actually made a post, lending credence to those who quoted you. If you want to go about destroying the evidence that you're not a jerk you can go right ahead; that's the price of editing a post, and you should always go into it being aware of what you're doing. However, you don't have as much leeway when it comes to destroying other people's defenses.
It isn't a perfect system, it can't be, and it doesn't need to be.
This is not, however, a good reason to make the system less secure. It will always be imperfect, but it's actually pretty good, and an intelligent person can usually deduce which parties have engaged in weaselery in short time (usually everyone involved if it comes to checking edit timestamps, in my moderating experience).
What possible benefit does this suggestion have that can outweigh the reduced load on our overworked forum staff? They don't have time to play Sherlock Holmes as it is, and there's no reason to make things harder on them.
Redunant points ommitted.
I figure mods can already see an edit history or something. Otherwise I could call you whatever I want right now and ninjaedit it once you've thrown a hissy fit and all the mods would have to go on is my post saying it's been edited. You can't punish someone for that, otherwise I could say that your post originally called me a doodieface and they'd have to buy it just because you had made an edit to fix a typo.
It's quite dangerous to make assumptions about what features this BB software supports (most places the mods use the same timestamps as everyone else, but not all). There's a lot of variance, and it isn't usually a good idea to tell potential trolls exactly what tools you have at your disposal.
