Suggestion:
I suggest we add a command similar to /auc spam to hide all lotto tickets being brought but only shows the winner.
Reason:
I really like to see who wins lotto but with /lot messages enabled there is always the temptation to buy a lotto ticket... Also a good way to not get your chat spammed with lotto tickets being brought while still seeing the winner.

I believe we already have the plugin.
