At this point I'll say I don't know anyone involved in this well. I vaguely know one person in a pleasant way who reached out via a mutual close contact. I didn't know of or have any sort of pre made opinion about the personality who is alleged to be doing shady stuff. Look in carefully.
I've noticed Saywa's own comments to you on this thread don't show up for me in any way unless I go directly to that person's account and replies. Only then am I able to see them, even after having turned any and all filters off. It doesn't look like I'm restricted from seeing Saywa's account.
