My "default" is to start with a private final member, set only by the constructor. No getter or setter!
Ok, we're all good, move on.
I agree that in most of the cases no variables should be exposes, in any matter, it is a statement of: "please side effects and bug, come and get me". In some env it makes sense because 99% of the time is about public vars (for example in Unity3d you have components, and you need to expose parameters of all sort so the game devs can visually instatiante and configure the instances, and ofc this leads to other big issues, beside the ones mentioned here).
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
