There are a few reasons for dislikes on Mangago you have to realize:
1. Trolls
2. People using it to say yes or no to a topic w/o posting
3. Feelings that a question is inappropriate for this site (art, advertisement, weight issues, etc)
4. They just don't like the topic, either because it is overly repetitive, complaining, or just controversial

Man, some people here in mangago can be really mean . I see dislikes in comments without any reason
