/vt/ - Virtual Youtubers

Okay, /#/ anons, I need your help.

I was checking VSTATS (pic related) and I noticed that Elira's stream in the daily rankings had a special notice next to it indicating that her peak was due to a Z glitch. I assume it's there because it would influence her place in the ranking because it would surpass at least one stream that's actually "ahead" of her without the glitch.

But then I took a look at the streams on the top of the tally and I noticed that Subaru's peak was also from a "Z" glitch and her actual peak is 37,729, which would make her stream 4th in the rankings behind Akina's 39,724 and that for some reason a similar notice is nowhere to be seen.
What am I missing? What's the methodology behind who gets this "!" notice and who doesn't? I assumed it was put there if the Z glitch influenced the rankings or at least the top of the rankings but that doesn't seem to be the case since Elira is 12th and Subaru would be 4th.
