Sort:  

It is because some user with a very high Hive Power downvoted some of your posts because they considered it "spam".

I haven't checked the notifications about it. Will check it later. If they don't want to see my posts better to unfriend me here. Sad, no freedom at all here.

That is why I (and many others) strongly dislike centralized blacklists ("spam hunters" and the like).
