Affiliates should be up front with their managers. If you don't want to get emails or IMs, say it right away and I think most AM will understand. Communication is key when creating a good partnership/relationship.
Weekly payments, a platform other than directtrack, offers I can't get at any other network.
I also prefer to be left alone by affiliate managers and to only talk to them when I want a payout bump or there is a problem. I consider "motivation" to be hustling. I like them to be on AIM but to not contact me unless I contact them first.
Seems most people don't feel that way. I usually go through 1-2 affiliate managers at a given network before I find one I can tolerate.
