It's hard to deal with spam and abuse even when there is such a team or effort. That's one reason Twitter is struggling, because unlike Facebook (where people can at least be semi sure only friends/family/connections view their content) Twitter is open to the public to view anyone's profile that isn't explicitly private. Moderation ends up becoming an awkward balancing act between not completely restricting freedom of speech and stopping trolls/bullies flaming the hell out of anyone they disagree with while simultaneous trying to make it scale. Which is perhaps even harder than determining between what's free speech and what's a threat/harassment. If someone can come up with a social network that doesn't discriminate between people from different backgrounds/with different political stances while filtering out actual trolls and which manages to do this on a large scale without a huge team of human moderators, then they'll likely pose a massive threat to the existing sites in the market.
