Hell yeah!!!
I don't think your case is directly sbi related because I don't see a % of crypto taken away even though there are dv on your posts. You haven't lost anything. Mmkk is now supposedly going after only those who sponsor others with a sbi share.
People, since the new update, can dv at will just about but I wouldn't worry about it too much, yet at least. People with power tend to go a bit nutty.
If you want to sponsor people in, the @steembasicincome is a good place to find your answers.
