Nope, no problems here either
However, a caveat. As Jel mentioned, there is some risk involved with pulling old recips. What if that particular site you pull does in fact still have you listed, but they simply haven't sent any traffic that month? I'd suggest checking stats carefully to ensure that you weren't listed...or looking for your listing at the link site in question. You never know when a small list will take off and you wouldn't want to get mistakenly blacklisted for pulling recips on a site that was in fact listed.
