i have several nics on my enemies list. many of them are tournament directors and most of those are acbl directors. i also have checked "ignore chat from enemies." i use the enemies list to keep my copy of the chat bar as uncluttered as possbile. i find all those advertisements by acbl directors to be unnecessary and frankly unwelcome. there are few players who have earned their place in my hall of shame on my enemies list. most are only there for a short sojourn, usually a few days, until they decide to stop sending me messages. i update the player notes for any player who makes an out of the ordinary bid, makes nasty comments to players at the table, quits in the middle of a hand, is nice, pleasant, friendly etc. i check to see if there are notes for any of the players at the table i am seated at. i date the notes as well and purge old negative notes if there have been no newer incidences. perhaps when a player sends a message to someone and it is blocked becasue that player is on their enemies list, the system should return a message and inform the sendor that their message was not received.
