The Global Blacklist API is a personal project I work on to provide a consumable API interface to my blacklist as well as other blacklist projects.

Projects can choose which blacklists they want to use and are not limited to just my blacklist. For example SteemCleaner's real-time list available as well.

Global Blacklist API 2.0 added major performance changes as I received better endpoints for the blacklists I support.

This update adds dynamic support to @smartsteem's blacklist.

Dynamic Blacklists Supported

BuildAWhale
SteemCleaners
Utopian-IO
Redeemer
MinnowBooster
Actifit
Oracle-D
Smartsteem (new)

The Global Blacklist API is a dynamic real-time API that exposes the above 8 blacklists via an easy to use interface. There may be up to a 30-minute delay before our API exposes changes to one of the above blacklists. More blacklists for well-known projects are being integrated and will be announced when available.

Choice

As a user of the Global Blacklist API, you can choose which blacklists you want to subscribe to. As other blacklists are added you only need to update your blacklist choices. I recommend using a configuration parameter that allows you to easily specify what lists you want to look for, or just check if the user is on any blacklist.

Integration with Blacklist Notifier Chrome Extension

The Blacklist Notifier Chrome Extension fully supports the Global Blacklist API and provides curators an easy way to know if a user is on a blacklist and which one.

The Blacklist Notifier is supported with Chrome & Brave browsers, Firefox support may come in the future.

Do you use the Global Blacklist API?

If you use the Global Blacklist API in your product or service, please reach out and let me know so I can gather a comprehensive list of projects supporting it. Last time I checked over 50% of popular dApps used the Global Blacklist API in some form.
