I think this premise is wrong. I haven't met any developers who think we are the only ones who suffer from interruptions. There are many lines of work that can suffer from them, some more than others. While your suggestions are good and should be used (not hacking code without some thought, breaking down a problem), I don't think that is a magic bullet for this issue. The planning is the part that is ripe for interruptions, coding once you have a plan should be trivial.
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.
