Botting

Is it becoming a huge thing to bot? i went about 6 months without seeing one and now I have seen over 10 in last 3 days. I am on a PvP server, so naturally blizzard has to do its thing before they can issue a ban or what not. So I farm them to keep them from doing what they are trying to do. A Friend told me that I can get into trouble for doing this. Is that a true statement? I do put in a ticket when I see them.
