Lately I have noticed something that concerns me - that some regulars on chats actively stalk and downvote certain other users' questions/answers.
While 'stalking' itself is harmless enough - well if you post on a public website, you want your writings to be read. Whether it is guided from the title, tags or from the search engines, or because, well, you are the poster. Stalking down someone, negatively commenting, downvoting his/her answers or questions doesn't seem to be a healthy hobby to me - esepcially when the links are posted on chats and other regulars are expected to participate in the downvoting/negative commenting. This is harassment, it is bullying!
This is different from serial downvoting - which usually happens when a user is angered by another user. It is almost like continuous serial downvoting, from a group of people who don't seem to have better things to do other than sitting in the chat, stalking others and amuse themselves with downvoting certain other users who, for gaining reps or other reasons putting an effort into answering questions.
Also, I have mentioned a couple of victim in the comments beneath. Here is a section of the transcript in regards to the user 'Your common sense', here is some search results in regards to the user 'vlad from moscow' in the C++ lounge - BTW vlad isn't aware of the C++ lounge.
BTW more upvotes doesn't necessarily mean you are right, see:
