I don't think acronyms were being used back in 1994. If they were, they would be used and recognized by a select few. Possibly by someone like Jimmy Olsen, the hacker, but not by anyone else at the Daily Planet. I think it would be okay to suppose that Batman was aware of the acronyms, since he makes it his business to know everything, and he would have the best computer that money could buy in his Batcave. But that still doesn't necessarily mean that the acronyms had even been invented yet. And what was the internet like in those days? Honestly people didn't exactly chat with each other via computers back then!
My guess is that the acronyms didn't exist. Smileys existed, but they were not widely used. And the most likely reason why they existed in the world of computers was that smileys were popular in the real world at that time.
