As a basis, I simply took the 7 mods that have CKII sub-forums. I'll avoid any particular names.
Out of those 7:
- 2 have ModDB pages (by their authors)
- 4 have GitHub pages (by their authors)
- The last one used to have a GitHub page. From what I hear they didn't stop due to the rules, but due to some of their users being dumb and making bug reports with the in development version without mentioning that they were using the in development version
All told, only 1 out of 7 is within the rules, and that one
used to break the rules and stopped due to their users being silly.
