Many users while voting do things like "per this user" and "per that user". However, people can abuse this. They may hate the user going for a rank on the thread, though they can't find any reasons themselves. That's why they would find a detailed Oppose reason and just go "per that person".
Besides, using pers is just being lazy that you can't type a good reason on your own anyway. Instead of saying per, you can say you agree with the user, and you must add something on.
This isn't supposed to be a voting thread, but you can go ahead.
