This question is based on a paper I came across a couple of years ago written by a famous professor who had developed a method to solve a certain problem. His method was not the first or the only method but it has some advantages and it is widely used in industry.
The paper I came across was written with sole purpose of finding flaws in a method for solving the same problem that someone else had published 15 years later.
Regardless of who was right, is this the proper way to deal with a flawed paper? This seems a bit weird to me. Do journals even normally publish such papers? Aside from citing the (presumably) flawed method, he also specifically named the authors in the abstract.
This worries me a bit because I plan to publish another method of solving the same problem soon, and although I have confidence in my work I don't think it's bullet-proof. I feel that if such a paper was written about my research it could have a significant negative impact on my future career if that was what popped up when you googled my name.
