Once again, Supergalaxy (super galaxy, super-galaxy) is no longer found on Wikipedia

 Joining other notable articles, like the non existent 

Gibson's Bakery 

 Mega Chad (The largest ancient sea)

and Bernhard Goetz  

No article for those, but "all your base are belong to us", something that doesn't actually exist, has an extensive article there.

Sugar in your gas tank

Short story, it will not destroy your gasoline engine

Not found on Wikipedia

I considered starting a topic, just for laughs

Super Galaxy under attack once more

Not A JOKE

Gibson's Bakery

 Even I am not going to touch this one.  While obviously the most notable bakery in the world at the moment, you just know the woke who run Wikipedia will simply not stand for it.

May never be found on Wikipedia

The Spite Store, found and not found on Wikipedia

 heh

Update on the Spite Store "topic"

 https://en.wikipedia.org/wiki/

While writing out the reasons for existence, I realized Wikipedia calls page "topics", not articles.  This explains a lot.

Skulking

https://en.wikipedia.org/w/index.php?title=Skulking&redirect=no

In a random way I came across an article for Skulking, under the article for spite

https://en.wikipedia.org/w/index.php?title=Spite_(sentiment)&oldid=180807603

But there is no article for skulking now.  That I found it because of the current edit war over spite store makes it ironic and hilarious, neither of which are found on Wikipedia.

OMG it never ends
