Steve,
The player stats are public information. These sites go thru a lot of trouble to collect them. I don’t think there’s anything wrong with collecting stats and providing them back to your players to increase their edge. However, spamming at the tables is against Party’s chat policies. I once reported a table spammer, and the spammer’s account was disabled for chat for one month as a warning. I was told that if he did it again, his account would be closed. So, there are ways to stop the spammers. Report them.
