If you ever manage to get into university, you'll understand why Wikipedia isn't a trustworthy source.
Here's an actual reputable source.

only an idiot wouldn't understand the meaning of illegal.
thanks for clarifying it for the moron anyways.
but again ill post this.
Illegal Trades:
No trades via PM. (It's harder to prove a scam via PM than from a trade thread, so always negotiate and deal through a trade thread, not PM).
Do not trade for / sell real life items outside the Donor Forum. This includes but is not limited to CD keys. No linking to any outside auction or trade sites.
Do not trade accounts, characters, or names. (Exceptions: Eve Online, Diablo II)
There's nothing "illegal" against trading keys, it might be against the sites T&C's, but it's not illegal.
