Deleted Characters Being Reviewed

This may be the breaking point for quite a lot of people. I wasn't affected and I still think this is horrible, even worse than all of the other horrible things they have done before this.

I completely agree.
It seems as if they've given up on feigning any hint of decency or responsibility.

I truly don't understand this situation. Who was supposed to benefit from the intended action?
Why even risk this move?
Hime (though she's an idiot, so it's understandable) talks as if the removal of some of the exploiters is supposed to make up for the fact that legits have likely now lost all sense of security.

They should have simply eliminated all Cannoneers and called it a day.
A bunch of script kiddies running around with two extra attack and a skill that will eventually be just for show aren't going to hurt anything.
If they wanted to save the game, they missed the chance when they let people get away with massive Chaos/White Scroll production, repeated dupes, breaking & entering of accounts, and (insert all the other acts of apathy here).

you have no pineappleing idea how much i agree with you, seriously, how does nexon manage to pineapple up to these levels, it's like they grab the worse that we expect, and use that as the minimum possible damage they can cause.

In this case, it feels like like they're just pineappleing with us.

I think they used the date of acquiring the skill, but put it like way back in April. Might be some Korean programmer entered 10-4-11 instead of 4-10-11 (or vice versa). Not enough data in the deleted chars list (too many people saying "shortly after UAs were created") to be sure, though.

That's still nonsensical.
Not every character with a UA skill is a UA.
Their first qualification for deletion should have been that a character was a UA.

Actually, it wouldn't.
They can't roll back individual accounts or characters.

I didn't once say the word "rollback", so I'm not sure why you're using it.

If they have a saved backup, they could individually restore characters from that backup.
Since they clearly don't have an automated system for this sort of thing, it would have to be done manually, but it could still be done.
Of course, the flexibility of this method depends on how long they keep their backups.

I agree with you (and others) who have said that the solution should be bans, not deletions.
There's no reason to go easy on people who would actively seek to exploit the game. Plus, it's clearly easier to deal with a false ban than an unwarranted deletion.
