It seems lately every time I go to a thread (from new posts) I see a new user who posts a link leading to a site for Behavior or housebreaking target sticks. None of them have anything to do with the topic. Most are posted by a "new Uer" who has no posts in the intro thread. So has are they doing this? Has the forum been hacked? or is this what they are trying to do? I hope admin can do something about it.
