Always good to avoid unnecessary complexity, but I don't agree with arbitrarily avoiding recursion.
There are recusions whose depths are easily calculated, and whose code is easily reasoned about. Remember, the speed of a solution is often better governed/adjusted at the higher level. (millisecond shaving by using iteration instead of recursion vs saving seconds by changing algorithm and/or data structure).
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.
