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 @steemstem's blacklist and moves to python 3.7.3.

Dynamic Blacklists Supported

• BuildAWhale
• SteemCleaners
• Utopian-IO
• Redeemer
• MinnowBooster
• Actifit
• Oracle-D
• Smartsteem
• D-Tube
• SteemSTEM (New)

The Global Blacklist API is a dynamic real-time API that exposes the above 10 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.

Over 50% of Steem dApps use the Global Blacklist API in some form.

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.
