I don´t see what is in it for the sub, but I would ask everyone to consider it takes TWO people to make such a deal (or whatever you may call it). The blame is not to be directed at one party only.

I heard about this issue, too. To be honest, I do not understand it. Everybody is looking to get what he/she wants - ok so far.
The Dommes do get gifts and money, of course...
But I do not understand what the sub is getting here.

From what I see, the subs get little to no attention/service back. The idea that someone should derive pleasure from giving and not getting anyhting at all is scary to me.

But then again, my likings are scary to other people as well... *lol*
