I think the word 'toxicity' really undersells the issue because it's more than simply 'being negative'. On the most basic level it accounts for things like abusive language that are already directly covered under the 'Prohibited Activities' section of the ToS and apply when you're playing in-game regardless. On the more insidious side it includes various forms of online harassment including brigading behaviours, which while also covered under the 'Prohibited Activities' section, can be a more complex issue to define.
As an example, if
someone like yourself were to post links to people's personal twitter accounts on this forum with the intention of inciting others to harass them online for their personal views, many people, some previous members of your own brigade included, would probably take issue with that sort of behavior. But it's not as obvious as hurling profanities at them.
And the frightening thing about this type of conduct is that if even the dev team members can be the subject of such targeted attacks, then it doesn't create a safe online posting environment for
any of us. Which is why we need the dev team to have an open conversation about it.
