I find 50% with a TRUE revshare (none of this uncredited crossales, consoles, or leaks bullshit) to be perfectly fair. Plus they are paying rebills at the old rate.
I'm more inclined to want to push traffic to them now because it seems less likely that they are going to pull an asshole move like these other programs going out of business and keeping the rebills and never making the final payout.
Now, if we see scumbag revshare programs trying to justify pushing the percentage down to 40% then it will be entirely different.
