and there are many more, I'll update the list later when I have more time.
I don't completely get what these members are doing--and more importantly, why.
Judging by their usenames, date of registration, posts history, all the users mentioned above are alts for sure.
No idea what they are doing or why they are doing it but, definitely, something fishy is going on and we will figure it out sooner or later.
