In the SCP Foundation Wiki (basically a fandom based on a creepypasta like wiki that have entries in a Laboratory esque manor) Homestuck is canon. SCP-2721 reads Homestuck. Give it a read, it's kinda interesting

I love the SCP Foundation! I believe I recall having read that SCP before, and I considered writing an entry for SCP-4130, but I have no idea what it’d even be, and also I think it’s not quite up to those numbers yet right?
