When attempting to upload a mod to the Mod Portal recently, I encountered this error:

Error: It is not permitted to distribute executable files with your mod. Please remove all files ending in exe, bat, ps1, sh, py. (code: 500)

The game itself loads the mod without complaint - it is only the Portal which has this restriction. Nonetheless, it would be nice to have some of these additional restrictions documented on the Mod Structure page, lest a potential author be barred from uploading their mod at the last second with no prior warning.

As another example, the page currently says this regarding the name field:

The game accepts anything as a mod name, however the mod portal restricts mod names to only consist of alphanumeric characters, dashes and underscores.
