Sites like just-dice have the most recent too, it was never random, you could add in syntax if you tip the last 20 or last 40, the reason just-dice has not a problem with it, is that people moved away from to different sites (like yolo) (it had the same spam problem like yolo in the past)
maybe ethan could add a 5 min timer on every user for a command, like you have to wait 5 min before you can do the next !btc usd command again, after you did it.
...also dont forget..rain which is given away is gambled which keeps the site active and if people lose their stash (i never hope for that) it goes into investors pocket...
So long - Racoon
