If you're scared of being iced but still want to follow TNT's suggestion of clicking through the actual link, check out this
petpage, which used to be Pigglletta's. It links to the
games, not the process-click links (with the possible exception of the slorg payout). That's what I'm using. It hasn't been updated, so most are dead links. Off the top of my head, this is what still works (in order as listed on the page):
Pack Attack
Son of the Mask (secret NP 250$$)
General Mills Commercials
Peanut Butter Cookie Crisp Ski Jump
Darcy's Wildlife
Survey Smash (secret NP 250$$)
Southwestern Indian Home (secret NP 200$$)
Sultan's Quest? (secret NP 200$$ -- I couldn't find any hidden NP, but I'm not registered as a Canadian -- I'm assuming since it's still up, those who are can get the NP)
Monster House: Yard Attack
Flushed Away
Rich Slorg
Petpet Adventures
and all the greeting cards you get NP for sending
As far as I can tell, this page follows TNT's suggestions exactly, so you still have to do the work (except now you won't be clicking on all the dead links). This will get you about 10-15k/day, I think (I'm too lazy to add it up myself), almost enough to buy your daily stocks.
(If there's something else that works that I've forgotten, PM me and I'll add it so that it's all in one place)
