Fortunately, each of us as users has the ability to bring this to DevTo's attention. I did the same today with someone I found doing something 'not against the CoC', but relatively questionable. DevTo is a relatively small team, so expecting them to be able to police everything is unreasonable, so then, it falls to each of us to assist as we are able to, by filing reports when we see things. We're like the 'neighborhood watch' xD
The one suggestion I would make -- Don't make it a 'public' ordeal, because you're ironically just helping that individual/organization out by making it even more focused in everyone's attention. Instead, send an email to email@example.com and they can investigate and take action behind the scenes.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
