The Checker Maven is having trouble with copyright trolls demanding large payments for the use of some of the images displayed on this site, and we're left battling their dubious claims. We have long displayed only images that we determined could be freely used, but copyright trolls will attack anything and everything, and it's time consuming and stressful to have to defend the site.

As an interim and not very good solution, we removed all images that were here before 2024, certainly not because of copyright violations but as a precaution to reduce the attack surface. The appeal of the "back issues" of our site will unfortunately be reduced. We apologize in advance. All checker diagrams will of course remain.

Longer term we'll use a service that will review all images for defensibility. The service is quite expensive and will cost about $500. This is perhaps the one time that we may accept donations to help defray the cost. We'll also be replacing many images with AI generated material. So if your favorite characters, like Sal and Marvin, suddenly start looking different, you'll know why.

This will all take a long time (months and maybe years) so please bear with us.

And to you copyright trolls out there, if you're reading this, please be aware that we won't read or respond to any email demands. Go through proper channels or send a valid DMCA takedown notice.
