The issue with logging in with email addresses has been resolved.
Due to issues with external spam filters, QQ is currently unable to send any mail to Microsoft E-mail addresses. This includes any account at live.com, hotmail.com or msn.com.
Signing up to the forum with one of these addresses will result in your verification E-mail never arriving. For best results, please use a different E-mail provider for your QQ address.
For prospective new members, a word of warning: don't use common names like Dennis, Simon, or Kenny if you decide to create an account. Spammers have used them all before you and gotten those names flagged in the anti-spam databases. Your account registration will be rejected because of it.
Since it has happened MULTIPLE times now, I want to be very clear about this. You do not get to abandon an account and create a new one. You do not get to pass an account to someone else and create a new one. If you do so anyway, you will be banned for creating sockpuppets.
Due to the actions of particularly persistent spammers and trolls, we will be banning disposable email addresses from today onward.
The rules regarding NSFW links have been updated. See here for details.
What is your definition of "clone", here? Clones in the RL biology sense are a superset of monozygotic twins and the non-twin ones are by necessity non-identical (e.g. Haruka/Kurumi, Yuubiseiharukana/Yuubiseiakikana).
The meaning popularized by science fiction, in which a clone is an exact copy of the cloned, down to memories. This same meaning being the one used in translating Kage Bushin as Shadow Clone in Naruto, a fairly well-known anime and manga.
In that sense, yes, it is. However, twins are about as close as you can get to that ideal barring some form of magic or science-fictional technology (there are theorems in quantum physics that forbid exact copying even in theory, although greater resemblance than identical twins is of course physically possible).
We're talking about fiction, on Questionable Questing. Reality has no bearing on this, unless you want to interpret the first post in this chain as intolerably monstrous.
