Yes I checked your votes and @blacklist & @steemcleaners have downvoted you a few times some are $1 downvote this affects your reputation number. Usually this is done if you copy from internet and post it without giving credit to original author or it could be comments if you have copied and pasted other comments. I looked at your posts but They seem ok other than 1 comment from cheetah who is a bot who will let you know they have found similar content on internet. Have a look through your posts and comments
