Ah yes, the genius plan of lying harder to their consumers. I'm sure all the criticism of CA and Sega will just disappear if they ban everyone currently complaining. After all, it's not like anyone could pick-up Warhammer 3 and realize it's a buggy piece of shit crumbling under the weight of ambition that can never be achieved.
They can ban them from the forums of the franchise and if you get this style of ban you can also lose access to uploading things on the workshop. So a prolific modder gets banned in this manner, it could basically mean the mod are static/dead (ignoring the ban may just already kill the enthusiasm for modding for said game)
