I am a pretty infrequent poster nowadays, but I like to pop in occasionally. If I see a good post, I like to pass around some rep. It seems against the spirit of rep to prevent rep to someone who happens to be on the list of that last people I rep'd, but it has been six months since I did it.
I would propose a 10 day or 30 day clean slate on at least that particular rep limitation. Not sure if it would be an easy change, but it has happened multiple times for me being an occasional visitor.
