Jigjag, I can’t speak for Malone but I am so ancient that “text speak” is definitely not one of my languages or scripts. (As to scripts, I’m probably closer in time to hieroglyphs.)
GWIT, like BRB (“Big Red Book“- ie, Chambers) is just familiar shorthand for people like me who spend far too much time on this forum when they aren’t spending far too much time doing crosswords.
