Got a warning from CFA Institute for using the CFA Designation (need advice)

These are the email exchanges between myself and CFAI https://imgur.com/a/tZ7esYR (orignal warning)

Also, the sarcastic tone in some of my comments were directed towards people insinuating cheapness among other things.

I don’t blame you for calling me a troll though; in this day and age, people are almost always considered guilty until proven innocent rather than it being the other way around

You say that as if it’s supposed to be the other way round.
