"The situation is at a point where it's finally calmed down."
Finally is right. This whole thing has been blown waaaay out of proportion by anti-fans and ex-"Queen's", or so they would have called themselves a while back. Kind of makes me sad that these are people who once called themselves T-ara fans and supporters. Some support they're giving, eh?
I've also started noticing that things are more calm than they were say three or four days ago. Hopefully this means that T-ara will finally start having some sort of peace.
Whatever the case, T-ara will take something from this. If the bullying is true, then they will learn that bullying has severe consequences. If it's not true, then perhaps they will learn that a few ambiguous tweets, followed by another ambiguous tweet can lead to trouble. And that their "fanbase" isn't exactly stable, so it'd be best to act accordingly. I do know that internal conflicts will arise. That's a given, and it doesn't happen exclusively to T-ara. Hopefully next time an issue arises within T-ara, they will know not to reveal it to the public and to try their best to resolve any problems they have.
