i was stupid enough to work on a new site for 4 months without a contract. I had good reasons to do that, but thats another story. I was doing white/ grey hat seo and tried to do my best. The site started ranking in a competiitve market (limousine service). Now my "partner" don t remember agreements we made. The domain belongs to him, but i have access to all accounts (analytics etc) and to the server. What can i do to harm the traffic (that i build up) without leaving a legal proof that i was behind. I don t care for moral advices, because i m the only one who build up the traffic.
