is cross-site trading allowed?

title says all i guess asdfghjkl just wanted to know if i can trade other pet site currency for sc/gc or if it's against the rules c:

It's against the rules:

Do not trade any game currency or virtual items outside the trading functionality provided in the Trading Centre.

1. a) We do not offer any support to "promise transactions". This is a type of transaction that doesn't take advantage of the implemented game's trading system or studding system to conduct a trade, studding, "reverse studding", or other action which involves an exchange of game assets.
2. - Code 2.6
