StopForumSpam API
StopForumSpam API

Your favorite and most trusted "one stop shop" for the prevention of forum & blog spam, trusted by over 200,000 forums.

Stop Forum Spam is a free service that records reports of spam on forums, blogs and wikis to name a few. All these records are then made available to you search and view but most importantly, to access in an automated way to block suspected spammers before they can get in the front door. Everyone is familiar with more traditional "solve the word" systems to prevent abuse, Stop Forum Spam is a targeted and specialsed solution to help stop abuse of your website.


No one likes spam, either posted through their letter box, emailed to them, a phone call just as you sit down to dinner or posted onto your website, sites that you have invested a lot of time and money in. In simple terms, it is an annoyance that wastes your time, drives your users away and in many cases supports criminal activities.


Free! Yes, free*

This API is NOT to be used as a general software firewall. Checking every incoming connection against the API will be treated as a denial of service attack against us and will result in the immediate blocking of any offending IP addresses.


We support:

  • Spam check by username
  • Spam check by IP address
  • Spam check by email
  • Spam check by email hash

Code Example

Below is a code checking whether IP appears or not in our database, and the number of times it appears (frequency).

curl --location --request GET '' \
--header 'apikey: YOUR PROMPT API KEY'

The only thing you'll need to change for checking (let's say) email, is the url to call.

curl --location --request GET '[email protected]' \
--header 'apikey: YOUR PROMPT API KEY'

Pretty simple.
