As the moderator who merged the two threads, the action will not be reversed. I did ask and was informed that the empty emails were not a result of Kobo being hacked.
The two threads were about the same topic, hacking was no longer an potential issue and the Empty e-mail from Kobo thread being created first were the factors in deciding which way to merge. I admit that "Has kobo UK been hacked?" was likely better as click-bait compared to the rather boring "Empty e-mail received from Kobo" but since no hacking was involved, the click-bait had no reason for existing.
Any further discussion must be taken to private messages.
