Stories held for quotas...

I'd just like to hear some opinions about holding up fanfiction stories for a quota limit. I have come across some authors that do that both at the fox site and fanfiction. Personally I don't finish them, because of this. I know reviews can stroke an authors ego, but this just seems petty.

I meant the fanfiction.net site!

Oh, I know. I hate it when I start reading a story and then they don't post the new chapter for about a week. I usually lose interest and stop reading. I haven't seen it done here, but I have on ff.net and on the fox.com Bones community thingy.

I totally understand if an author needs more time to post a new chapter for whatever reason....but I hate it when they just say "I don't post until I get xx reviews"
What about the other readers?
They do not count or what?
