Our blacklist has had a primary focus since the beginning of our first listing. Our primary focus was to list the websites that are offering things for free after the user completes an offer but after the offer the user soon finds out it was just a scam and the thing they're supposed to get for free was to encourage the user to complete the offer. We noticed that websites hosting these scams are not actively blacklisted and therefore we made it our aim to blacklist as many of these abusive websites as possible to allow internet users to be aware of the scams.
The first service to begin using our blacklist was URLVoid.com. URLVoid is a very popular website reputation service which empowers internet users to check a websites reputation before they access the website. Upon finding URLVoid we immediately agreed that it would be perfect for our blacklist to be used by the service to alert internet users of abusive websites that we list. You can find Spam404 on the "About Us" page. The same company behind URLVoid also own and operate ScamVoid.com. ScamVoid is a very similar service in a sense that abusive websites can be found using ScamVoid's domain search but we believed the nature of the websites we blacklist would also be important to be on ScamVoid.
Just this week we got in contact with Web of Trust which is undoubtedly the largest website reputation service on the internet and we felt it very important for such a service to use our blacklist. We are pleased to announce that Web of Trust now use our blacklist as a third party source. An example of our blacklist being used on Web of Trust can be found here.
We are currently in talks with other services so we will ensure to keep you updated if any other awesome services use our blacklist.
