@Mike Gorse Ah yes this has not occured to me when boosting their post that links to a blog article about amazon kindle books obfuscation.
Looking at the account it's apparently someone sighted with no relation to blindness and acb might be an accronim of their nickname.
They are more than three years on fedi already and more than 800 people are following them so it looks like a coincidence their name is clashing with the abc acb now better. It looks legit to me.
