First time I wanna say "hello to al" , I work here of 2 years (with 7 month) , I wanna ask customers why they enter in my room and don't answer to my "hello"
1. I'm polite with all
2. I answer to every guy
3. Never ask for tips , pvt or something like that
4. I have a great attitude in free chat and smile much time for they (they don't have to dislike my room because im never sad or angry or something like that)
5. I have great shows and not expensive , and I do it well
I don't need money to speak with a customer but I wanna know why the customers don't speak with me ?
I really waiting for some answers from customers please ! 
Let me preface this by saying that I've not been in your room before (but maybe I should!

) But you ask some good questions.
When you "Hello" to someone entering your room, are you actually saying it with sound so the customer can hear you, are you typing it, or is the "Hello" auto-generated? I ask this as it could make a difference in responses to your question. I am much more likely to return a greeting if it's actually personal, either verbal or typed, rather than auto-generated. I've had a "Hello" from a performer who wasn't even on camera/in the room -- camera on an empty chair! And this has happened several times. This sort of situation will likely NOT get a response from me, and indeed I'll move on to another room. Another situation I've encountered is a performer flexing/posing/etc and a "Hello" is auto-generated, the performer obviously not able to type anything or doesn't verbalize it. To me, this is not personal; it's very impersonal. Just sayin'!
The rest of the things you mention, sound to me like you're doing the right things and I would encourage you to continue doing them. This is what some of the most successful performers do all the time (cough Pacco Alencar cough) and it generates a lot of business.
So...keep doing what you're doing! You sound like a performer I'd want to visit!
ETA: Just thought of something else to add. One thing that's very annoying is performers who have very loud music in the background, so some of us turn the volume down on our speakers when visiting rooms. IF you're saying "Hello" verbally, it could very well be that the customer (such as me) didn't even hear you because there's no volume. If so, you may want to follow up any verbal "Hello" with a typed greeting as well, so we as customers won't ignore you, or seem to do so.
