I'm assuming that you're referring to my edits to your post: Only assuming the universe evolves according to a positive trace-preserving map, is there a proof that all subsystem evolution must be CPTP?
A summary of my edits:
An attempt at correcting grammar, adding MathJax, and adding a relevant tag:

A further attempt at improving grammar and sentence structure; adding full
name of the paper, (along with the names of the authors) so that it is later searchable
using the search bar and search engines, instead of just [this paper]<link>
:


An attempt to improve sentence structure of the title; trying to avoid uncommon short-forms/abbreviations in the title:

I did want to include the assumption "the universe evolves according to..." but was restricted by the word limit.
Removing the irrelevant tag "quantum-decoherence" after this conversation:

An answer to your question:
Even if you have 10,000 points because you're on here all the time, it
doesn't mean your edits are going to always be good.
I wholeheartedly agree with this. Yes, it doesn't mean my (or any other user's for that matter) edits are always going to be good/useful. I really would prefer an option to "suggest edits" even though I have the privilege to single-handedly edit posts without others consent. I personally feel that's one of the flaws of the Stack Exchange system, but I don't think that feature will be introduced in the near future. This probably has already been raised several times on the mother Meta.
From the editor's point of view, it is sometimes really difficult to judge beforehand whether their edit would make the OP "less-than-satisfied". I normally try my best to make useful edits like - improving formatting, improving grammar, adding MathJax, etc. However, yes, "human errors" are possible.
The best possible courses of action for you (in cases which you
desribe in your question) would be simply:
Leaving a comment for the editor (by pinging them with a @ followed by their user-name) and telling them to not make any further
edits without your explicit consent.
Using the flag option just below your original question and writing about the issue to a moderator.
Dropping into the main chat and mentioning the problem. Moderators do frequent the chat.
I think that at least in the initial days of the site, since we are all still in the "learning phase" of "how to manage a site as a community" it would be much better if you directly but politely point out any problematic issue you are face (with proof) or mistake(s) being made by any other community member, instead of being implicit about it. I don't understand how the issue of "at the expense of someone's dignity" comes up. The first step to stop someone from wrong-doing is to make them aware that they're doing something wrong! :)
