This question on renormalisation in quantum field theory had a number of comments under the main question, including one of mine; they all seemed to have been removed without any indication that they had been so. How come?

  • $\begingroup$ Comments, such as this one, are not expected to stay around. Other meta questions, and mother meta, reveal the mechanisms for that, including robots and miderators. $\endgroup$ – Jon Custer Dec 19 '17 at 13:51
  • $\begingroup$ @JonCuster Wait, robots? I know about the dead-question robot, but I don't know about any similar process for automatically removing comments. $\endgroup$ – rob Mod Dec 19 '17 at 15:21
  • $\begingroup$ @rob - if I recall, one of the bots flags long comment chains for human action. That at least makes them culpable, and certainly can be blamed! $\endgroup$ – Jon Custer Dec 19 '17 at 15:25

    $\begingroup$ I guess this comment chains going to get flagged for human action ;). $\endgroup$ – Mozibur Ullah Dec 19 '17 at 15:36
  • $\begingroup$ @MoziburUllah-In the first comment, Jon Custer writes about mother meta. Is that a person or what. Or did he made a typing error, by unintentionally writing an "m" previous to "other", resulting in "mother"? I guess the last is the case. $\endgroup$ – Deschele Schilder Dec 27 '17 at 12:02

    $\begingroup$ @descheleschilder "mother meta" is a colloquial name for Meta Stack Exchange. $\endgroup$ – David Z Dec 28 '17 at 23:10
  • $\begingroup$ Mother meta sounds good in the sense that it is a nice (?) alliteration, but nevertheless, I think I like grandma meta better! $\endgroup$ – Deschele Schilder Dec 31 '17 at 18:19

Comments are for criticizing or clarifying the question or for linking related questions, not for suggesting possible answers - that's what answers are for. The comments that have been removed were largely of the latter type. Comments on Stack Exchange are ephemeral and you should not expect any comment to be preserved indefinitely.

For more discussion of this, see discussions about deleted comments on our meta and on mother meta.
