InputMapper will be going ad free for everyone in the very near future. No account needed, just no more ads.
I am still working on adding cloud functionality so users can share and download profiles that they create for games. Sharing a profile on the site will be behind the donation barrier, still only $2 and all current donors will have the ability automatically. This is for 2 main reasons; first, donation status is the hands down best bot protection for allowing upload of content to the site. Odds are if you have given the site money, you are not a spam bot. Second, the load on the site from within the application will mostly be for cloud purposes so it seems fitting that the cost associated be tied to the same functionality that creates it. The manual download of profiles from the site will likely be free for everyone since using the site helps generate revenue through the ad's on the site.
1.6 and earlier will not be as easy to remove ads from, but I can make it so that any attempt to log in with even a fake account will be met with a donor status credentials within the application.
