I don't remember online discourses on filter avoidance for Grok to be any different from typical ones, except that it allegedly have tendency to take porn-biased interpretations of prompts, I think the "uncensored" pitch they had for a while was pure marketing in the end.
A few months ago it was the only model that would make children in pictures naked. I think that's been patched since Elon got sued over it.
Was that actually benchmarked and compared, or was that some British activist group insisting? I thought it was just the latter.
There is/was the official bot on Twitter that you can tag with a prompt, like "@grok put this spacesuit on a horse on a moon", that's not equal to being uncensored.
