Lets be honest, if I really wanted to get mad dosh with my mods I wouldn't be using external sites (5mods) to host my content, I'd set up my own website and hosting, a la GTA X Scripting.
I wouldn't hop into another site and try to change how it works so I can get more money.
I'm completely against the idea of putting adsites as intermediaries to downloads. Anything that bothers the player just so I can get money is not right. The plan is to get paid because they enjoy my content, not use them as a clickfarm.
