http://www.sankakucomplex.com/2009/12/27/otaku-christmas-seiyuu-stalking-mania/Each Christmas, 2ch otaku start a “Supervise female seiyuu to make sure they aren’t spending time with a man” thread, in which they pore over seiyuu blogs for suspect updates, check for possible alibi, and examine the dates of any photographs posted to make sure they are genuine evidence of a Christmas spent alone.

Of the various seiyuu monitored, it appears Ayana Taketatsu (Azusa) and Yoko Hikasa (Mio) are lacking proper EXIF authentication of their whereabouts this Christmas. Aki Toyosaki (Yui) has been spotted manipulating the EXIF data of a photograph to make it appear recent, despite it being identified as older.
The reason for the EXIF data checking is that the EXIF timestamp added to images by digital cameras will give away a photo taken before it was actually posted, in case seiyuu have the gall to employ subterfuge in defence of their privacy.
Naturally, a sufficiently savvy seiyuu (or more likely their agency) could simply manipulate the EXIF data to give an appropriate alibi, so fans also look for additional cross-site corroboration where possible.
As 2ch puts it, this thread is “90% virgin, 100% stalker.”
However, all this stalkerish suspicion is not entirely a product of obsessive otaku delusion.
In 2007, famed bikini model Aya Hirano made a series of Christmas updates to her blog in which she emphasised that she spent Christmas Eve, in Japan largely a romantic evening for couples, at a party which was “nothing but women.”
