Bugfixes, updates

Hello. Just a note to drop in the blog about bugfixes and updates being performed around the site.

As you may have noticed from the front page news section, the front page spammers now run off of a cache that updates every 5 days. This increases the page loading time for a better experience on the site.

I also found a bug in the API where old wildcard e-mails were not being searched in when performing an API call. The SQL has been updated to include this older data which includes around 3700 wildcard e-mails.

I have also tweaked the process that automatically finds spammers in the API logs based on heuristic information to include …. well …. more heuristics. Based on some preliminary data, this should increase the amount of spammers added to the database by 50%.

Thanks for reading and here’s to a great 2014 for FSpamList!


Speaking of Milestones…

We’ve recently just hit the 10 million mark for spammer hits in our database! Thank you all for your participation in the project.


Hello everyone! Long time no update. I’m just dropping by to say thank you for the past 5 years! I can’t believe it’s already been that long. I remember messing around with some crude code 5 years ago while I went around collecting spammer information from forums.

Fast track 5 years later, we’ve seen 9.5 hits pass through our spam filters (almost a half a million unique —more stats). That’s a far cry from the few thousand we saw in the early days.

So I just want to say thank you for your continued interest and support of FSpamList (Forum Spam List if you didn’t know). Here’s to another 5 years (and hopefully more improvements 🙂 )


I’ve done a few things in the backend to make things run a litter faster.

First, I’ve moved all of the spammers that haven’t been seen since 2009 out of the main db, but still made them searchable via the web interface. The API calls no longer will have to sort through those.

Second, I am now caching a large number of the latest reported spammers so the API looks in the cache first. The cache is updated daily.

As for a new feature, I have taken out the old “threat” level system that was basically useless and turned it into information you can actually use. The new threat system automatically gives a rating to each and every spammer based on a number of factors such as when the spammer was reported, when it was last seen, and the number of times it has been reported. Values close to 0 are more of a threat. In the future, I would like to implement a threat history so you can see how a spammer’s threat has increased or decreased over time. These threat levels can be seen on a spammer’s profile page.

“Add” Page Removed

In the interest in keeping the spam database full of only legitimate spammers, we have decided to stop accepting spammers via our “Add” spammers page. We are currently developing a set of tools that will provide other means of collecting spam data for your protection. Thank you all who have submitted spammers via that page in the past.

We look forward to continually serving you.

Export Page

The export page has been updated with a captcha system to prevent automated abuse.


I know some of you have had to wait a few days for your registration to be processed, and I thought I’d inform you of why.

The reason for the delay, is because the website you tell us you own, is checked for it’s content (i.e. whether or not it’s malicious). This may seem a bit OTT, but this is an additional measure to prevent bad guys getting hold of API keys to poison the database.

If you tell us you own yahoo.com for example (and yep, we get quite a few of those), your registration is rejected. If you do not specify a website, your registration is rejected (remember, fspamlist.com is primarily an anti-spammer database, for use with forums, guestbooks, blogs and websites).

API Limits

New API limits have been imposed on both the new and old “check” APIs. The limit is 5000 per day. If you or your scripts exceed this, you will be met with a general server error. If for some reason you need the limit expanded, please contact us.

Also, please report any errors you encounter.
