I think aside from the tweets, all the bullying "evidence" can be questioned. It's all up to the interpretation, but there are some that now give me the shivers (but I may not have thought of as anything significant before).
Jiyeon missing Hwayoung's high five was the first gif that made me think "ouch".
Then there was a gif of Eunjung having a blank expression when Hwayoung was being spotlighted at a sports event:
It wouldn't be so weird out of context because sports events are boring, but those random boyband members look more excited than Hwayoung's own group mates. What?
Then there was the video of Eunjung stuffing a rice cake into Hwayoung's face. When I saw it for the first time I thought "oh ok, guess she's trying to be funny", didn't think much of it, just thought she was playing up for the camera. But the stare she gives Hwayoung before approaching her, and her expression after... now that it's pointed out it it's kinda creepy. There are caps here:
http://pann.nate.com/talk/316364914There's also Jiyeon tweet that's bothering me, but that one I'm confused about because it's said to be from January, but JY fans are saying that she stopped using twitter until February. ... But either way, it'd be Jiyeon ranking #1 on some popularity poll and then saying "poor Hwayoung got 0 points, keke". And that would be completely unnecessary...
There's also Jiyeon pointing out on Star Life Theatre that Hwayoung is just reading a book in the car because there's a camera there. "I've never seen her read a book before during the time we've been in the same group." I understood it as a joke watching it, but I noticed that Hwayoung wasn't really laughing along with them at that very moment, but seemed more awkward/embarrassed, which I already thought was a little weird then but didn't think much of it because the show moved on to them all dancing to music in the car or sth.
All of this could be nothing, even if NOW it seems like "evidence". On the other hand, it's not like they are going to call her names on camera, so little hints are the best we could get anyway, about any kind of bullying.
In any case, whether the "evidence" is just coincidental and not related to any kind of bullying at all, it doesn't change the fact that the tweets themselves were upsetting on their own as proof of the girls' unprofessionalism and that Hwayoung was targeted.
I have a feeling (not knowledge) that their relationship with Hwayoung has been a bit of an upside down U-curve - as in, they weren't close at first (obviously), then most of the members warmed up to her (so there are lots of pictures and videos of them being physically close, holding hands and things)... but recently things have become worse again. I think this because most of the more incriminating "evidence" is quite recent, like the girls not helping Hwayoung off stage with her crutches, random reports from the recent Idol Olympics thing (although there are also pics of Hwayoung sitting with T-ara members), the rice cake video and of course THE TWEETS.
I've read a lot of horrible comments about T-ara recently because I've been reading just about everything trying to get more information and see where people are standing with this. While I'm extremely disappointed and upset and angry at the members who were my favourites and think they deserve some rough time for their actions, I don't want to be as hateful as some others are being. It's tough. Even if the girls have this ugly side to them, I don't know if that means I should forget about all the goods sides that they have. Maybe in time some kind of resolution can be achieved, but it's way too much effort to keep trying to love people who don't seem to deserve it right now. There are plenty of other Kpop groups out there that don't have constant drama like this. STILL WAITING FOR THAT ANNOUNCEMENT, I GUESS...
