In the following question: Are there any irrational/transcendental numbers for which the distribution of decimal digits is not uniform?, I distinctly remember adding a comment about "God being lazy and tossing dies to generate important irrational numbers". When I visit the question now, I can no longer find that comment. I don't even see any notification saying it was removed. I swear I saw it just a few hours ago. Can comments be removed from questions without notice?
Yes, comments are often removed by moderators without notice, often in response to a flag on the comment by some user. Indeed, this is one of the main activities of moderators.
Many of these removal are also harmless. The reason for removal is merely that the comment is not (or not anymore) necessary, at some point this was called "too chatty" it now became "no longer needed." (Of course, we also remove rude comments. But the point I want to make is that this is not the only reason, and in fact not the most common one.)
This is what happened in the current case.
Since comments are ephemeral, I've putting my opinions into an answer. As many users notice, moderators can remove any comments without prior notice. Nonetheless, it would be better to suggest some of the possible reasons that your comments get deleted.
As the name "Math Stack Exchange" suggests, we communicate in math on the main site, so it's important to keep the site focused on math. To avoid an overflow of comments which doesn't help understanding the problem, those comments should be cleared.
Your comment doesn't make sense for atheists, who don't believe in existence of God. Since posts here are supposed to be neutral in religious belief, I don't think that's a suitable comment on this site.
