It's not just a Trulia issue - they are on HotPads.com, Craigslist and any other internet site that allows consumers to post ads. Trulia is VERY aware of the problem but is in a quandary - they want the public to be able to post rental ads like the other rental websites. In reality, especially here in the SF Bay Area, VERY few rentals go through realtors and the MLS, so if Trulia limits entries to those that only come through Realtors and the actual MLS, then there would be virtually no rental listings here at all.
Additionally, because the postings are free, there is no income to provide a paid monitor on Trulia's side of the fence - thus, just like all the other websites with rentals, they let the site be monitored by those who actually use the site.
Trulia has tossed around a number of ideas as to how to control the situation, but so far does not have a viable solution that is not fee-based.
Additionally Trulia picks up listings from other websites. Not all of the scams were posted directly to Trulia.
It is fairly easy for a person to spot many of the postings as a scam. If a computer is used to decide what is a scam, generally there will be plenty of people who can figure out how the computer makes the decision and trick it into doing "evil".

A suggestion to Trulia, if the advertiser does not have their listing posted through our MLS, Trulia could charge for that listing to be posted. In my opinion this would bring income to Trulia, weed out some of the scammers, and possibly allow Trulia to be able to track the scammers back to their payment.
Sorry, it doesn't answer your question or solve your problem. Awareness is the beginning of improvement. And when more users voice their concerns, perhaps the developers and host will be open to make some changes. I have heard from other agents who used to be very active on Trulia decide to stop contributing because of the amount of rental issues.
Actually, we know about the scams. The Trulia community of agents give reminders all the time.
If they are able to post ads, that is disconcerting.
What will be more convincing that noting it here, though, is a letter.
If you are STILL expecting to see actionalble information sourced from Trulia or Zillow, you may be one of those.
Serious buyers and sellers will promote themselves to usiing serious data resources.
