If someone wants to describe LW as cultish, they can take any parody of itself and present it as further evidence for their claims.
I think something like this has already happened with the Chuck-Norris-like list of Yudkowsky facts; the "Bayesian conspirator" illustration of the beisutsukai stories; and the redacted lecture screenshot that displayed "Eliezer Yudkowsky" on the right end of the intelligence scale. -- Instead of "they are cool people who can make fun" they can be spinned into "this is what those people seriously believe / this is how much they are obsessed with themselves... they must be truly insane". See RationalWiki:
That Eliezer Yudkowsky Facts page is the most disturbing thing I have read in my life. I don't need a shower, I need the outer layer of my skin peeled off. (...) It is fanboyism at a disturbing level. (...) he is hosting this shit on his website that disturbs me
On the other hand, if someone wants to describe LW as cultish, they could also use lack of parodies, or whatever else as an evidence. Once you are charged with being a witch, there is not much you could successfully say in your defense.
So at the end, perhaps we should ignore all such considerations (which, by the way, is what most non-cults do) and simply upvote or downvote things only by their own merit. Also, any attempts for this kind of PR automatically destroys themselves if it is easy to provide a link to the discussion about the PR. (And LW being LW, such discussion will almost certainly happen.)
I'd still be happy to remove the EY facts post, although I've been hesitant to do so because it would affect many other people's comments and hiding things might itself be construed as sinister. (I guess your point is that it doesn't matter, but I thought I'd mention it.)
My stupid fanfic chapter was banned without explanation so I reposted it; somehow it was at +7 when it was deleted and I think silently deleting upvoted posts is a disservice to LessWrong. I requested that a justification be given in the comments if it were to be deleted again, so LessWrong readers could consider whether or not that justification is aligned with what they want from LessWrong. Also I would like to make clear that this fanfic is primarily a medium for explaining some ideas that people on LessWrong often ask me about; that it is also a lighthearted critique of Yudkowskyanism is secondary, and if need be I will change the premise so that the medium doesn't drown out the message. But really, I wouldn't think a lighthearted parody of a lighthearted parody would cause such offense.
The original post has been unbanned and can be found here, so I've edited this post to just be about the banning.
