The whole point is downvoting in such excess destroyed reputation to (-4), you know yourself it is easy to destroy reputation of a person and it is often not possible to gain it again. Was it not enough to downvote 2 or 3 and also to leave a comment under downvote? Or to offer technical advise and professional help we do that in my medical field if we feel that my colleague need help no matter if I like him or not, that is what we have to be and not to destroy each other especially witness number one to destroy other witness, that is not good advertisement.
