I was reading an interesting news story about the online advertisment community Craigslist and housing discrimination. It really hit home with me because I had a similar experience where I had emailed a female advertising a room, and she never replied (which I hate, but no biggie), but I check the ad a few days later to find that “Females Only” was added to it.

As far as removal of the ads goes, it should be the same system they use now. If a post is flagged enough, it gets removed. No need to bring law enforcement or anything into it.
