Hey man.
Thanks for the offer, it's very kind, but I'm respectfully going to decline.
Even with all the drawbacks (you mentioned some of them) I prefer to be a free agent as that best suits my main goal with being here;
I'm here to offload keys I can't use, in a controlled environment. I do know that sometimes it spirals out and becomes a lot more than just ridding myself of keys, but those occasions doesn't come even remotely regularly - more like on the schedule of when I feel like it ;-)
Sadly, it just wouldn't work with any group using any form of the ''tit for tat''-regulations, or point-systems which are usually one of the cornerstones of yours and similar groups. Don't get me wrong, I'm not bashing, I don't mind these groups at all, I'm just saying it's not a good fit for me.

I am flattered by the invitation, and I hope you find someone else to fill the spot.
Have a good one, TPDragon!
