In other words, I highly doubt that the same effort would have been invested if it was not Quickseller in question, I have not been here long enough but I can easily guess that Quickseller did a lot of "terrible" things to many of you, therefore, I can't blame anyone who will use everything at their disposal to "win" something against Quickseller.
Again, it's hard to argue with a hypothetical but I think you're overestimating the effort it takes to notice a sockpuppet of a cancerous trolling scammer like Quickseller. It's really no more than just reading a post, seeing a weird word or phrase, and copying it into a search box, and that last part is mostly optional when you've been around for a few years. Most people just wouldn't care enough and that's fine. I kinda had to care since Quickseller had some grudge against me for something, tried to dox me, etc, so I prefer to be aware of sockpuppets of such individuals.
Not trying to "win" anything here. There's nothing to gain for me.
