A question on accounts

So, I made an account. It's all for the Horde, everything I do is for the Horde. But my friend, well he plays Alliance. I finally got him to play this game, but I thought that you wouldn't be able to make an Alliance character after making a Horde character on a PvP server, so I did the only thing I thought to do: Make a new account. Now, I'm not going to be botting, finding out what the sides are up to or cheating. I just wanted to play with my friend, BUT if this is against any form of rules or it's just something I shouldn't do I'll stop. Like I said, there's nothing bad going on with it. I personally am extremely against bots, having to live through it in Ragnarok (oh god the horror).
tl;dr I made a new account to play Alliance with my friend, is that good or bad?
