So basically on a question I attempted and failed to answer, I have been following it because I am interested in the solution. People have been posting answers to solve it (some similar or identical to mine). Since I've been looking at the problem the whole time I felt an obligation to tell some people they were incorrect (maybe a bit too insistently). However after one of my corrections, I noticed my reputation suddenly drop; when I looked at the cause I noticed that two of my questions (which is all of them btw) had been simultaneously downvoted. The chances of that are very slim (since the questions have no recent activity) so I assume someone got angry at me correcting them and decided to lower my rep.
My question is: is there any recourse for this or any way to tell if I am just being a suspicious person?
