In other words, anything beyond records and memories (which are a form of records) hasn't been shown as something within the phenomenon's influence. Aside from making people die, obviously. If Chibiki is to believed, it's neither malicious nor sentient/conscious , and as such probably wouldn't do anything beyond providing the initial grounds for Another to exist once again, then running it's natural course.

since I'm speculating a bit, not much, I'll put it under spoiler tags

Spoiler for speculations:

Yes, it would fit well the supposed unconsciousness nature of the phenomenon, even if it is quite scrupulous, for not being sentient, it erases only the relevant part within a whole process of investigation, more like it didn't work in advance, but along the story, as with the Kuoichi's father case, it looked unready of that accident. Even with the tape it erased only the old Another's name and not the whole tape or the memory of it. Like it was not omniscient. But like it was ... sentient. A student would fit well that logic of erasing. I'm stating the obvious here, I know. Ok, sorry I went astray a little. eheh
Speaking of Akazawa dream, it is something that shouldn't have happened, if it was a real Another doing. Or so I think.

Anyways what I was trying to do in my previous post was to connect the two supernatural cases. Because, you know, one supernatural case is cool, two are too much So I'd like to connect them together. But you are right that even if the phenomenon is sentient or not it alters the less he could to go on. It is not bothered by who but by what. It acts like a filter.
Plus we don't know yet what would happen if Mei said that name. But if she should say it for real there is only one way we could think of for the pehnomenon to prevent her to say it aloud . . . . . . . . kill her.
