The idea is that these names are generated pseudo-randomly or arbitrarily because they have no brand value. Sellers that use them run through "companies" quickly as they get banned for forbidden practice or because their reputation tanks. Then they create the next seller account with another name.
I've been wondering why I do like Twitter for long form content. At first, I hated it. But then I got caught up in several long threads, and invariably at the end someone would link the threadreader collection of the whole thing. I kept thinking, I'm just going to start going to the bottom and looking for that link, but I never did.
Instead, I learned to love it. It's almost a way of being reminded again and again about who is speaking, and it gives you a little feedback of how interesting other Twitter users found that particular section.
I don't really like that I learned to love it. I think it might be unhealthy. But that's a different issue.
That article was a bit of a bait-and-switch: instead of explaining why the Chinese resellers all use similar patterns, the author just spent 30 twitter posts complaining about being undercut by cheap Chinese crap
Related, I don't understand twitter as a place for long form content. It's difficult to read and it can't be easy to post.
