There are some people who just think they are more intelligent and have over confidence in themselves. And they cannot accept any comments against them. And they think everything as negatively. So it is better not to engage in arguments with all these type of people. This will save you both time and effort
Unfortunately people who do not have any problem with being annoying and that is something that I could definitely be understanding if they were doing it somewhere else, but there are many online wherever I go, I believe that being annoying online doesn't matter to them because they do not face the people they are being annoying to, if they were face to face, they would feel humiliated to be such a bad person, and would act a lot more nicely, but they are not and they are online so nothing is off-limits, what will people do?
Since legal moves look like it would be silly, it is even worse and that's why I feel like we shouldn't really be caring about them at all.
