This task involves the work with converging on what people will experience when they attempt to reference a source that a project has determined to be unreliable while editing using the visual editor. //A parallel effort for the 2010 wikitext editor is is happening in T347435.//
Where "unreliable" in the scope of this ticket refers to a source that exists on a given project's `Special:BlockedExternalDomains` page.
//Note: we can see a future where Edit Checks presents people with feedback about source beyond those that projects block from being published. Tho, this work will happen in TICKET once, at a minimum, T346849 is resolved. [i]//
=== Story
**As a person** who is unaware of Wikipedia's [reliability policy](https://www.wikidata.org/wiki/Q4663914) and who is attempting to reference a source that the project I'm editing has deemed to be unreliable //and// unfit for publishing on-wiki, **I'd value** being made aware of this information and presented with an easy and timely way to act on it, so that I can publish the change(s) I'm making and increase the likelihood that they remain on the wiki before I've "moved on" from thinking about sources.
=== User experience
//This section will eventually contain the proposed user experience for, what we're calling, the Reference Reliability Edit Check.//
