That you can't see the value in having such a team - that having such a team is essential for a company like twitter to operate - is completely baffling to me. Not having one will make advertisers pull out and make the company much less profitable.
Advertisers can be spooked by the contents of tweets. Basically few brands want to be associated with extremist or otherwise 'damaging' contents but that's very different and rather touches moderation. That's why advertisers are currently cautious, not because of Human Rights (capitalised) in global conflicts...
