Yeah, I do still have my twitter account but I try to avoid going on it and only still have it because there are a few niche times where it's still unfortunately the best place to get current information on local issues (last Sunday for example there was a power outage in my area and the power company's twitter is a bit better at giving updates than their official site so I was checking both).
I really wish I could just delete my account and maybe I still will (and just create an empty dummy account for those rare cases so twitter doesn't harass me to log in). But to be honest I'm less stressed about social media in general ever since I left twitter and I suspect over time a similar thing will happen with being off Reddit.
Unfortunately I don't know how to report magazines/users so I can't help you there but I just want to add my support to what you're asking because this sort of thing is against the kbin terms of service:
