>>215321It was erased from 4chan servers, but archives have the post archived from before its deletion.
Most if not all the boards have an archive, but they are all hosted on different sites, big ones include archived.moe, rebeccablacktech, and desuarchive.
If you're using a userscript like 4chan X or Appchan, and possibly even in the native extension you can have 404'd posts redirect to the archive on hover and shit, see pic related
Or you could just manually search the archives for whatever you're looking for, it's good for looking at shills and shit on /v/ and /g/
