I've just noticed highly suspicious download activity on my contributor account that appears to be automated bot activity . how to contact support team ?
Not if there are multiple projects. Each project would require a separate license. In any event, whether you contact Adobe or not, if it is indeed suspicious activity, your account would probably be disabled while Adobe investigated. But if you want to contact them, you are certainly welcome to do so.
