Badrepping is part of the territory, so it is allowed (within the boundaries specified in the FAQ). In individual cases continuous badrepping can be seen as harassment however. Using your ignore button works better.
Where is freedom of speech then? If I disapprove with a post I should be able to bad rep it.I think I don't disturb anyone as long as I don't offend poster in w comment.but anyway just saying. I will use ignore button
