I was often struck by the fact that the women on video chat seemed able to type without looking at their keyboards!
I eventually figured it out.
Here is an experience I suggest you do: when invited for a "live" video chat with a lady who is "online" I suggest you ask her to do a specific movement, like for instance "put your hands behind your head". You will only too often get a "Why?" or any other reaction that will become increasingly aggressive and is just meant to keep you in the chat AND TO HIDE THE FACT that it is not a LIVE video at all but one that was recorded previsouly and re-re-replayed again and again.
In fact "she" is not online at all, someone else is typing for her and keeps you sucker paying by the minute.
Not all of them of course... just too many.
Hence I would recommend... caution.
