I'd be prepared to donate money to a subbing group, but most seem uninterested in this (perhaps because of the negative consequences?). Most have also proven to be pretty unreliable, subbing one or two episodes before getting bored and moving onto the next thing.. I also believe TV Nihon took donations to buy DVD's at one point, and then never bothered to sub the series.
So yeah, perhaps best not to pay anyone for this sort of thing.. There's a lot of seasons I'd love to watch, we just sadly have to wait.
