user5198: A question was recently (<48° ago?) asked on Biology Meta by Masi, regarding research-type questions. I was the only user to answer. The question appears to have been deleted. I haven't seen this done on other SE meta sites, even when the questions and answers were far more contentious. Was it deleted by a mod?
As a new user here, I am concerned that I am responsible for it's deletion. Was there something amiss in my answer? Did I break some kind of site etiquette? 
This is not an attempt to defend myself. I'm looking for honest feedback about this site's etiquette. I won't argue with answers (I hate that). I'm just confused. I tried asking in private but was instructed to post a question in meta (et viola!)
Thanks.

user8804: I feel there's a latent polemic developing around @Masi 's questions, as can be noted from the recent downvotes/closed questions he's getting, and the extended discussions in comments trying to make sense of it all. Masi seems of good intention and holds a repectable amount of rep points. However, it is quite difficult to interact with pure speculation and poorly formulated elements unsupported by research litterature (in questions as in answers) without affecting the site's functioning, given this site's vocation to transmit scientific knowledge and thought.
So now what?

user6: The question was self-deleted by the author. This is possible in this case because there was no upvoted answer, the only answer had a score of zero.
Moderators can undelete such posts, but I don't think this would be particularly useful in this case.
