I have noticed several times the same person editing low quality questions. The most recent example is this one. However, this edit simple replaced "fourier-fourier" (which is an obvious mistake and should only appear once) per "Fourier-fourier".
At the time I made my comment on this question, I was on mobile (and I am still), which makes editing harder. The question has several issues:
The title was wrong and low effort.
There was a direct link to an image instead of an actual text stating the problem clearly.
No effort was put at all.
I flagged that question but it remains open. But that's not my concern. The person having made the edit clearly didn't put any kind of effort whatsoever, and I noticed the same person usually does this on a regular basis.
Is there a way to punish such fallacious edits? I would say this is reputation abuse to farm points and is going against the website. The person could (and should) have put more effort into the edit, suggesting they didn't even read the body in the first place.
I don't know who reviewed my flag, but I wouldn't be surprised that this were the same person. How to justify that such a question is still open then?
