They might not want to join your groups or something, It happens to me too, that's why I invite friends really now, since no one else likes to join 
I need to know why?
Some people might be in too many groups and don't wanna join. Others may not use groups at all. Don't take it so personal.

Do you really thinks it's possible that all the hundreds of people I invited have that same problem?
Look, i am not gonna be in any more groups. sorry, but that is the end of the story.
That's okay, I know that already, I haven't been sending you invitations.
Well, the point of a group is to get together people with a common interest. If somebody does not have that same common interest, then they have no place in your group. It's not personal.
Perhaps inviting random people to your groups is not the most effective strategy.
Also, many of your groups only target a very select interest, so it is unlikely you will find people that share it. Even when they do, they might not join your group. For example, I am interested in Super Metroid, but not particularly interested in joining an SM group on a chess web site, particularly a group that can't remember where minibosses are located (The Spore Spawn is in Green Brinstar, not Crateria).
i hate it too. whenever i send like 10 invites, only 1 person appears only! it's so weird!
If I were to receive a group invite like:
"I saw your recent thread/took a look at your recent games (delete as appropriate) and think you would be a great addition to our group because ....."
I would seriously think about joining but when I receive the mailshot sent out batch style, you are just wasting your time. Why would I want to join some massive group with ill-defined parameters that seems intent on Chess.com domination through shear strength of numbers?
I think I speak for many on this site when I say that all impersonal group invites from people I don't know/have never spoken to, will be filed in the bin without consideration.
It got to the point where I was receiving so many of these scatter-shot group invites that I finally turned off my ability to be invited.
For those that want to do the same you can find it here:
My Home->Account->Privacy
If you can believe it, though, even after noticing that I wasn't accepting group invites some members have decided that working around this restriction by posting the invite on my notes will change my mind.
I agree with PrawnEatsPrawn, though that if it is made personal and the reason for the invite explained and well thought out I might actually be inclined to consider accepting.

Those who I invite, why don't you accept? Have you got something against me? I'm trying to build up a group, but I always fail because of people like you (I'm not talking to those who actually accept them). I use about 15 invites a day sometimes, and I end up empty. This probably won't get any of you to accept (knowing you from the past), I just want everyone to know.
