I hope by tracking you mean tying it back to who initiated the misleading article. Not just who wrote it but who paid for it and to what gain. Then once a year publish a chart showing the top ten sources ,and their most published topics/titles of misleading articles, from source to publication.
Only if the ads are contained in secret nanites you ingest that play subliminal ads to your cerebral cortex when you are at rest making you crave the sponsor's products forte nightly! My logic and 'direct to cortex buy now' -TM suggestions are undeniable.
Ah, Craigslist sucks.
1. Their interface sucks.
2. They won't fix it.
3. They won't let anyone else solve it for them.
If third parties are not supposed to scrap data for their users from Craigslist CL's Legal team should be all over sending a C&D to Google! Sure that's not going to happen because it would be stupid, but so is killing off Padmapper. A great interface that keeps Craigslist in mind when someone moves into a new place and wants a TV or Couch, or even a date. They will look back and wonder why they didn't try harder to grow with these third parties instead of killing them.
Oh, now programmers are graphic designers too? Don't want to play the submit three logo comps and maybe we'll hire you game?
Geez, even a hired gun has to shoot someone for free once in a while just to show potential employers he's still got it! No one really knows what you did before (unless you have code groupies). Employers certainly do not give a shit in today's job market, they want to know you will fit in with the team and that you work as advertised. No one in their right mind believes advertising or resumes these days. So what's the alternative? You want to slip them source someone else paid you to make! I sure as shit would not hire you if you share like that. Competitions surely suck for losers who do not learn from their loss(es).
Suck on this - if you are bored then YOU are boring. If you won't build a small (not going to make anyone else money) solution to show a potential employer you can, you probably can't.
