Already someone cheating? On reply, they write the same four words (reply, might, found, backs), then there is a pause (while inputing the results on a solver?) and then the right answer. Why bother?
I have no doubt that people will use bots on this, but what you're describing doesn't actually sound like anyone is cheating. Because of the way the game scores, there's not really an advantage to taking your time, so it quickly becomes obvious that the best strategy is to use the same first 3-4 words on every game, and then pause to try and get the actual answer.
