If it's on the web it will stay on the web, but only if you want it deleted...
On the other hand if you think it should stay there "forever", it will most likely dissappear quite soon, so you better make a copy while you can...
Then you can post it somewhere again sometime.
Maybe, just maybe...

all the black holes, the astronomical ones
are in fact some sort of giant garbage collectors?
