Why are TI calls not listed in LIVE NOW usually?

LIVE NOW=2016-02-27_18-24-55
I have been selecting the Live Now button every time I connect with talkshoe. I usually have no luck finding a TI call Live Now, except for today. Do you think that someone doesnt want to have any TI calls visible in Live Now so no one accidentally or not signs into a TI call. This would mean anyone would need to know the call is on to join in.
