Guild Wars 2

So I joined a game with 3 people in it (me being the 4th) and when I got in the person on my team wasn’t really moving, just running out of the start and then standing there and getting killed without fighting back at all. I thought it might be a bot or something so I reported it.

Then, a while later a guy/girl on the other team said he/she was controlling the character on my team in addition to their own, and basically just farming them for kills :o!!!! He/she said it was not cheating because they owned both accounts. I quickly left because I didn’t want to be involved in this since it didn’t quite feel fair.

So my question is, is this cheating/botting or what? And is it normal, or should I report people for it? I’m new to pvp (only a rank 10) so I’m not 100% on how things are done, your feedback will be much appreciated!
