IMO it is absolute bush league to publicly call out a player for "potential" cheating. this goes for either side. you may have your suspicions, but unless you can prove it - which you can't - it is NOT ok to run around dragging someone's name through the mud. what is this, guilty until proven innocent? for all you know you are dealing with a professor or wordsmith or even just a bright person who has been an avid word game player for years. yes, many dirtbags cheat, and i have been highly skeptical of numerous opponents, but even in the most seemingly obvious of cases i would never call out someone's name in a public forum.
listen, as troublesome as the losers who cheat are, nothing is more galling than being wrongfully accused. there are countless seasoned and skilled players out there, and IMO one should exercise restraint in tossing out accusations each time an opponent demonstrates strong wordplay.
