Yes, it's perfectly safe; any number of you incredibly persistant little twits can call out the 1st three numbers all you bloody want; the only responses will continue to be other twits, just like you, about 2 per week, calling out the same three numbers.
Do you all call this "chatting"?
Have any one of you ever seen anyone respond to you in the chat-room?
How long will this insane "123" banter go on... oh wait a minute... theres twenty chatters right now! because I typed those numbers, I bet! Oh my gosh, there you all are!! It's magic....[/i]
