Sometimes things are doing by misguided employees in the false assumption that they are helping. It's not the company that is doing the deed often but an overzealous employee who doesn't think of his/her actions. We experienced this with forum posting from a competitor. When we found and I talked with the owner he was as confused as me, but he phoned me back a few days later to say that he had tracked it down to an employee. He apologised and contacted the forums to remove the posts - I had a lot more respect for them after that. We're still competitors and fight hard, but fair, with one another
