2 ideas:
1. stolen bike finder button should stand out a bit more. maybe in red (btn-danger)
2. Dont have a stolen bike but is there a way to flag listings so that other browsers know they are browsing a stolen bike. Might auth with a social network and require a couple friends to flag it as well (so individuals dont do it maliciously). But would massively improve your data and would help the community self police.
Many bikes photographed in the same spot. Poor-quality photographs (blurry, etc.) that make it difficult to pick out distinguishing marks. Very little detail about the bike's components.
None of these are proof of a stolen bike, but each is a useful flag, an indicator that the ad is worth further scrutiny, and flagging could help people looking for their bike.
My thought was - recruit your friends to flag it with you. When things get stolen you normally tell your friends, who tend to be sympathetic. Better than no flagging, though I admit this can be gamed quite easily of not policed well (one set of users flagging several bikes could be of concern for example)
