Looking back at her TA diary (on 03/19/11), it seems more like she said that because she hadn't really released anything in that period.

Her appearances on shows have been rather nonexistent during release periods anyway... especially recently. I remember NEXT LEVEL was promoted with like one performance of Rule? I think it's just gotten to the point where she likely just isn't as interested in performing on TV unless there's something pushing her to do so. (like the quake, or being invited which may have been what happened for FNS)

Her appearances on MS since 2010:
04/02 MUSIC STATION SP
04/16 MUSIC STATION
09/10 MUSIC STATION SP
12/24 MUSIC STATION SP

03/25 MUSIC STATION <-- the earthquake episode
09/02 MUSIC STATION
09/16 MUSIC STATION SP <- the one she missed due to being stuck in the US

So it's nearly been about a year since then with one album inbetween that got mostly radio promotion. We'll see when her next release comes out and hopefully the Tales of Xillia 2 song gets promoted more like Love song than You & Me.

Anyway, I highly doubt she was actually banned and she's just been slowly pulling back on TV performances in the last few years to the point where they rarely ever happen at all.
