From mass emails to web sites
Today, scammers have a much better way to reach more people on a more personal level through social networking and dating web sites. Many web sites are very familiar with scammers, the pictures they use, the mass messages they send and most of all their real locations as opposed to what the scammers put on their profiles. Based on this, it should be very easy to keep the scammers from even signing up or at least catch them once they start sending their mass messages. Sadly, high member numbers and traffic seem to be more important than member safety.

Unfortunately, we had to delete your profile for spamming....no, we will not reinstate the profile. Evidently, posting comments on a profile with links to a graphics comment site is ok but links to a scammer information page to warn others is considered "spamming".
Warning from a dating site

A moderator noticed abuse on your profile and provided the following reason: "Stop posting comments that are abusive to other users." If [site] notices further abuse, your account will be blocked. A Scam Buster recieved this from the site for posting warnings on scammers profiles.
No matter what good you try to do in this world, there will always be those against you
The Frustration Almost anyone who has been a Scam Buster long enough will tell you that scammers are not the only obstacle they face. What's more frustating than dealing with scammers is trying to warn others on the sites and suddenly your account is deleted but not the scammer. Sometimes it seems like it's ok with some sites to warn others but warning too many brings an awareness that the site has a big scammer problem and that can give the site a bad reputation. The end result is almost always to delete the one member warning others instead of reducing those high member numbers and traffic by getting rid of the scammers.
The Reward Anyone that has been on the larger social network or dating sites long enough has seen the many volunteers who actively seek out scammers and try to warn others. These volunteers, often called Scam Busters, devote much of their time to what is sometimes a very thankless task but the reward of knowing someone might have been saved from a severe financial loss or emotional devastation is well worth the time and effort they put into it.

Try not to get so wrapped up in a picture of someone that you ignore inconsistencies, flags and warning signs
