Why are the answers disappearing on the site?

Question

Toaster

I noticed that in exactly two topics I created, user responses were missing. Why is this happening? I doubt that the answerers themselves deleted their messages. Missing answers somewhere 6.

Answer 1

Also noticed. Most likely users themselves delete. If the answer is not marked as a solution, then it can be deleted, thereby increasing your percentage of solutions (shown in the profile). Well, or they delete it so as not to litter the question with answers.

Answer 2

it is not correct to answer for all users... personally, I delete only those answers (my own) that are clearly not answers to the question (and let's say they were written with a gross error). I am guided by the fact that sometimes I myself need to find something ... and in the answers to my question I really want to see something that will help solve the problem, and not constructions like "null == false", button accordions or jokes and so on. Therefore, if you write an answer, then it should really help / work.
If my answer is partially an answer (for example, for certain conditions) - I leave it (sometimes with a postscript).
upd
also, it cannot be ruled out that some ... umm ... monitor their "indicators" in the profile, and if a person does not mark "as a solution" or does not click "like" - they delete their answer so that "does not spoil the statistics"
