I once reported few duplicates posts. Most of the posts were buried because they got a lot of downvote... People didn't care that the same post was posted yesterday and is still in the top page. They did not care that another post was added an hour ago, 5 hours or a week ago and this one is not news anymore and is also a duplicate. In addition, breaking the posting rules here.

In addition, one day I submitted a few posts via the report option. Nothing happened, the posts are as they were. And my account probably got a shadow-ban because I could not make entries (only I saw the entries, others did not) - and it was probably a reward for reporting violations of the rules, although I am not sure, because I did not receive any information.
