I dunno, I post almost entirely in bullshit, yet the insults have yet to begin. How much more bullshitty does it need to be?
If it's funny/creative/witty bullshit, then it's pure acceptable.
If it's misspelled, includes unnecessary "Xs" and "Zs", and essentially the equivalent of an old dementia infested woman with hemorrhoids shitting on a keyboard, then I'd say that's grounds for insult.
