.. what functionalities the chat in gambling site should have and why?
Requires some minimum balance or waiger requirement for a certain user to be able to post message on chatbox.
The required amount however should be not that much.
In that way, trolls will be minimized. There are people who will just register in a site to spread
"something" on the chatbox and will not actually play.
We know the tendency of spams when theres a chatbox that is completely open for everyone but it isnt necessary coming to a point to have that wager requirement.
On my part even i do have the money to play or wager on if i cant chat directly this will really somehow affect my interest (this is based only on my own).
This is why theres a chat moderator to handle spams.
