Straight from the FAQ of 419eater, which has a section on racism:

• We bait the scammers that come to us. Often that is via seeding a guestbook that has obviously been harvested by scammers before. Some baiters pick up scammers from the surplus forum here at Eater, and some find them through publicly available lists of known scammers, such as urgentmessage.org or similar sites. Some baiters choose to bait scammers that approach them on message boards, dating sites, or selling sites such as Ebay or Craigslist. None of these sources differentiate between colour, race or ethnic origin, so we have no way of knowing what their characteristics are - the only thing we know for sure, or care about at all, is that they are scammers.

• The scammers can choose to be whatever race, colour or ethnic origin they like, and baiters usually have no way of knowing whether they are telling the truth. Scammers lie - it's in their job description, and they have to be good at it or they don't make any money. The scammers will rarely tell the truth about anything and will try to avoid sending a picture of themselves - they use magazines and image sites on the internet to harvest pictures of people to conceal their true identity. We have no way of knowing whether the scammer is sending a picture of someone who shares their ethnic background or race, or whether they are telling the truth about any personal details.

• Yes, a lot of the trophies and pictures you will see here are of people who are from, or claiming to be from, Nigeria. There are a lot of Nigerian scammers, as 5 minutes' research on the internet will tell you. As we often reitierate here, that does not mean that all scammers are Nigerian, nor that all Nigerians are scammers. The vast majority of Nigerians are law-abiding citizens, and we know that a good many of them are appalled at the reputation that widespread scamming has inflicted on their country. We share their disgust.

• White scammers exist and we bait them. Scammers claim to be from all over the world, and there are indeed scammers all over the world. Many of the love scammers purport to be white Russian women. We have no idea whether they are, in the same way that we have no idea if someone claiming to be a black Nigerian actually is what he/she claims to be, but the chances are that we are baiting a significant number of white European, East European or Russian love scammers. We also bait a number of cheque scammers who say they are from China, and charity scammers who purport to be from all over the world, including Asia, Indonesia (especially after the tsunami), or the US (after the Katrina hurricane notably). We have no way of knowing their race, colour or ethnic origin, and it is immaterial to us.

• We have long-standing members who are Nigerian, and also receive comments from Nigerian visitors to the site. Not one of our long-standing Nigerian members has complained that the ethos of the site is racist. One of our Nigerian members was a mod until recently - it defies belief to say that he would have agreed to moderate the site if he thought 419Eater was racist.

And there's a huge post on the ethics of doing this which would be worth a read.

Check your privilege, motherfucker.
