In the chat people mainly get into chats with other people.
So if i was having a conversation with somebody I would hardly look what others are saying, because I'm talking to 1 guy.
Many of people do this and it would be better if when you came into the shout box you looked who was online, Who was talking then say something like "hey everybody"
Not just "who wants to"
Because if you say Hi, People will see that and most likely respond.
Your not exactly getting ignored its just people are in their own world when they are talking in the shoutbox, They have their own conversation going or most likely really busy.
You never know, You might be saying it at wrong time when a mod gets you for spamming.
Like the mods may be busy, Then when ever they check the shoutbox the first thing they see is your question, Then go back to what they are doing.... Then come back into the shoutbox and see you asking the same question.
Its happened to me before, I know how it feel's lol, Just bad timing
