Establishing boundaries through Warnings (which arguably is what they're there for...) is the best way to go about this.
From what I've seen, the community is getting half-baked sanction postings and not every case having full transparency or all information given from what actions and reports go through... Where is the warning system?
Needs using. Certain people's actions have been upsetting the community for a long time and all this "we will wait until its sanctionable" isnt a good outlook for staff. Address the issues before they grow on a more reasonable approach and i think the likes of reports and sanctions would be more justiiable to the community as "You were warned."
Just my two cents. Oh. Here's one more cent:
If you keep trying to force the community to tidy up after these issues, there's also going to be displeasure. Part of the problem is that we as players are being asked to sort the issues out when there's clearly tensions. More often than not, a report is because the VR sender is no longer willing to deal with taking out said issues to the opposing side in the altercation. Staff going "Yeah, please stop this. Its not doing alot of good for the community and is making more friction than neccesary" is a simple approach that can benefit everyone in the short and long term.
