If this is indeed the case, Buster and Medium is "ramping up efforts" to cut down on spam and fraudulent accounts, I have one you can focus on. The guy who gained over 4k followers in about a minute and a half and then another thousand within a couple of days. His grand total is somewhere around 179K. And, he can't write. That would be a good place to start, don't you think? Instead of weeding out the chaff for writers like myself? I'll be happy to tell you who it is. You know how to get in touch.
