I'll take this for the forum admins, so they don't have to. As the thread states, they only allow for one name change per player, since you already have got your name changed once, they will not want to change it again.
The first post says that a second name change request might get ignored - not that it would get ignored automatically. Also, there should be a rule regarding getting old names back.
Did this statement also refer to jkwon's request and mine? The original name change thread got hidden and no clear statements were made. Honestly, I feel treated unfairly. You cannot come up with a new rule and apply the rule retroactively. I once saw someone's name changed three times and now it's not even changed twice for long time members. And there's good reasons to change the names a second time in our cases. I did not even want to go by jkwon in the first place, like said before blaataap didn't get the joke.
