This question already has an answer here:
I would like to know what is generally accepted when it comes to serially going through a user's posts to correct grammar/make edits. I do not intend this to be antagonizing in any way, and I really wasn't sure of how to phrase the previous sentence properly and concisely while not sounding kinda like it.
Sometimes I see a user who has a post needing editing, and for one reason or another I'll look at his profile. If I also happen to navigate to another question that he has asked/answered which looks intriguing it may also be one that (I think) needs editing, though I don't edit it.
Now I've only gone so far as the first edit (the one I inadvertently stumble upon), because I'm still on the fence:
Will the user find it odd/annoying/infuriating that I've gone through every one of his posts to edit them? I'm talking about real edits; I'm not looking for easy fixes.
Does the benefit to the content of the site outweigh how the user may feel? The consensus on things like "Hi", "Thanks", etc on posts leads me to believe that it might.
Sometimes these are posts that receive very large amounts of views. So these posts are very visible to Googlers and others. Since these posts seem to attract a lot of people, and in doing so seem to represent the site/draw people to SE, shouldn't they be as clear as possible? I would think yes, but if I happen to find a post through a user's profile (because it looked interesting, probably due to the number of views it has) I don't believe I'm impartial anymore.
Since I would be making suggested edits I would certainly not be filling up the review queue with this kind of stuff, but I feel like this might apply to those who can make edits freely as well. I'm not sure if this is considered bad etiquette, especially since the user may feel targeted (regardless of whether the post needs editing).
Short version: Is it acceptable to serially edit users?
