Sometimes, writing words is OK (if somebody said them earlier, labels, etc), but users will often nervously warn a player out if they start to write, just to make sure they don't cheat.

I had one table where a guy wrote ABC and then inserted ABaCus, which was the word. Someone guessed it before we could warn him out.

The reason people are so quick to warn, and so willing to try cheating, is because there is no long-term incentive to be a fair player. When playing pictionary or charades live, participants worry about their actual reputation with their friends or colleagues too much to try to cheat for a 'quick point'.

We need some sort of similar incentive. Ways to allow this may be:

1. Allow 'warn' for up to 15 seconds after guess.
2. Store a % warned out as stats for each player, displayed prominently on their profile or perhaps even on the game page.
3. Decrease points for a user who warned out.

At the same time, it is important to make sure that warning does not become a bullying tactic. I have not seen this happen yet, but some safeguards may be required.
