EVE New Citizens Q&A

B. Selling Items and Objects
You may not transfer, sell or auction, or buy or accept any offer to transfer, sell or auction (or offer to do any of the foregoing), any content appearing within the Game environment, including without limitation characters, character attributes, items, currency, and objects, other than via a permitted Character Transfer as described in section 3 above. You may not encourage or induce any other person to participate in such a prohibited transaction. The buying, selling or auctioning (or any attempt at doing so) of characters, character attributes, items, currency, or objects, whether through online auctions, newsgroups, postings on message boards or any other means is prohibited by the EULA and a violation of CCP's proprietary rights in the Game.

While Im sure that many people do trade in-game currencies, ISK is the intellectual property of CCP and your subscription only pays for you to access their property. Trading or transfering it violates the EULA.

How does this in any way address the OP's question?

Under what rule?

bolded the important parts for you.

Those parts refer to EVE items, not items from other games.

So I repeat: how does this answer the OP?

It doesn't matter what your trading. What the OP wants to trade is irrelevant it could be Battleforge points, dollars, yen, brightly painted stones or tree bark. If you take any out of game item for an in game item and it is not a sanctioned system such as PLEX you are in violation of the EULA, which happens to be exactly where the quoted portion comes from. There are alot of other things in it, you might want to go read it.

For Your Clarification:

Direct from the Eve Online Terms of Service

10. You may not market, sell, advertise, promote, solicit or otherwise arrange for the exchange or transfer of items in the game or other game services unless it is for in-game sales of in-game services or items.

11. The advertisement or sale of out of game goods and services not directly related to EVE online is prohibited. The only out of game goods and services which can be advertised or sold are the following: EVE forum signature creation, website and third party voice communication server hosting or EVE Time Codes.

Despite the derailment about things like PvP smack talk in Local often breaking the EULA, etc., you can and will get the immediate banhammer for trading items from another game for isk. Very recently - like a month ago, maybe? - another new player came to this very forum completely confused and upset that he was banned with no questions asked because he had been "trading" Diablo 3 assets for isk.

Don't.even.think.about.it. End of story.

Since you brought it up, though, even the "You may not abuse, harass or threaten another player" line in EVE's EULA has very clear precedent for how it is enforced, and no, in the EVE universe, simple Local PvP smack talk does not break the rules. What does break the rule is making the fight demonstrably personal against a player and there are notable incidents of this occurring -- so notable that in at least one fairly recent case it even made the wider gaming media.
