I'm just guessing here but I'd assume this is a knock-on effect from Stan Grant's resignation from copping abuse, if individual show's accounts are closed and they just leave the general news or sport accounts you would think people are less likely to associate those account with a presenter of a specific show to target hate towards that individual. We also have the recent industrial relation laws around the employer's responsibility in providing a mentally safe work environment.
Nah - the ABC was pretty big on its twitter integration. We had a few long running, decade+ old forum-style shows where people could/would tweet in live to be part of the program.
