There's really no reason for them to be honest about this sort of thing and I've seen plenty of shady shit from moderation here to make me distrust them.
Which isn't me asking for an explanation/stance. However trustworthy you find the moderation to be here, any explanation they give is inherently biased towards an obvious desire to remain employed.
From my perspective - this is a forum/social media site that is popular and _not_ infested with ads. It seems obvious to me that what they do gain is influence with a certain group of people (investors) and as a filter/brain-drain/funnel for entrepreneurs.
