To be honest, while I do see his point to some degree (just about every webmaster forum has become an utter cesspool due to a lack of moderation and a flood of idiotic posts and signature spammers), I'd also like to point out that being too harsh can kill a site just as quickly. For one thing, it makes newer users feel a bit too scared to start contributing, especially if everything slightly below quality standards get removed immediatedly. And given that a community depends on new people as its lifeblood, the result can easily be an ever dwindling pool of site veterans talking among themselves til everyone loses interest and stops visiting. So you want to remove the obvious idiots and poor contributors, while not scaring away people who might otherwise become decent users in the process. There's also a related issue you need to consider here, and that's that to some degree, you need to avoid being too strict in terms of what's 'relevant' to the community. If you've got a programming forum, it may seem tempting to shut down any 'low quality' conversation about unrelated matters like TV or films or sports or whatever else, since they're not related to the site. But people don't purely talk about one thing over and over. It's best to have a place to discuss these 'unrelated' things (with some semblance of quality control) so as to bring the community closer together and to see other members as friends and associates rather than just virtual colleagues. In other words, keep quality up, but don't brutally remove anything that's even the slightest bit dodgy or shut down everything not 100% related to the topic, otherwise you'll likely end up with a perfectly immaculate ghost town.
