Hypothetically speaking, 2 min per post = 30 posts in hour = 240 posts in 8 hours. They have to eat, go to toilet and login to different accounts(I'll remove 2 hours from their shift) - that is 180 posts a day, on weekly base that is 1260 posts, as you said they have to post 10 posts a week so one person can operate 126 accounts without problem.
9 laptops, 9 persons = 1100 shitposting accounts.
And that is just the estimation of bitcointalk posting. Bounties are massively spammed over Facebook/Twitter/Medium accounts as well. I'm pretty sure they would have 100's of social media accounts to make the most out of bounties. This is hilarious! Can't believe they have started a company for bounty whoring!
