To sum it up:
A pdf was directly posted withe filename: "removekebabmanifesto". Not sure by whom, perhaps Tarrant, he mentioned him by name.
Shared links to pdfs from Breivik, Crusius, Gendron, Krajcik, and Palmeter.
More links to pdfs published by "Terrorgram" one titled "Do It For The 'Gram". Judging by the title/description these are accelerationists works encouraging committing terror acts, and offering guidance on how to do them.
Long lists of links to various extremist groups' telegram channels.
There was a longish post with stuff like:
> If you are ready to go full Breivik [...]
< then do this or do that.
Though I have to say the don'ts should be kept in mind. With the addition: don't be stupid and fall for this shit.

Yes, there was definitely a smearjob on Endchan, which still appears places like the article about imageboards on Wikipedia. People use baseless accusations to defame the site and the users.
