Over the short run, it is the campaign managers responsibility to prevent lots of crap posts coming from the campaign. However, if over long periods of time, if a manager allows lots of shit posts, and doesn’t do anything about it, it will reflect negatively on the person who didn’t fire the campaign manager in favor of someone who would address the shit posts.
The manager can only do so much given the pay rate.
I forgot how to check who's on DT2.
Go to any profile he left feedback on, and add ;dt to the URL. If it shows up, he's on DT.
