The account that posted the (balderdash) response was created in July 2020 for what it seems is the sole purpose to troll $ISX directors.
Interestingly it does have one follower but you can enquire into this on your own.
One other observation is that "balderdash" term is likely to be used by an over 50 demographic (one could also make assumptions about the ethnicity of the person that would use such a term also) as its not common vernacular these days. I wonder if KL would use the word balderdash by chance?
Note I do not post much on here but have been an interested onlooker for over 12 months now.
