There are a lot of people who can only access a computer once a day, or who otherwise cannot sit around waiting for arbitrary posting limits to let them post again. If I have roughly twenty minutes and five RPs, I should be able to reply to them all, IC and/or OoC (in my case, granted, OoC, since my average IC post is around two thousand words and will take up all of those twenty minutes), and maybe reply to a couple of discussion threads while I'm at it.

	Time on site and number of posts are [b][i]no[/i][/b] indicator of the person's judgment or lack of vindictiveness. I've seen an actual mod with over two thousand posts and five years on site silence people who did not agree with her, as well as another mod who took to harassing specific users off-site, and a couple of other incidents - now multiply those accounts by number of active users this, not exactly small, site has. 
	Furthermore, people do tend to move in packs. If X votes that, so, chances are, will their five friends.
	[quote]And of course all such should be reviewed by mods later on.[/quote]
	Then as far as mods are concerned, it would be no different from actual reporting feature. The exact same amount of work.
