Four links (which say "Backwards Incentive" when you hover the cursor over them) give you 20 CP's, +10 for clicking, and another +10 for actually voting on the site. So 1960 CP's is the max per week, if my math is correct, that is (which it's probably not :P).
If you were to click each link, every day, for a week, and voted on each of the four double incentive links, you would make, with bonuses and all, a total of 3,360 CP's. There should not be a way to get more than that from voting, though other things get you CP's.
