Yes sir, I totally agree with you as these kinds of practices are spoiling the immense hard works and efforts by the people who are trying to make DTube better. And recently many whales have started to vote DTube's content and the other whales would get a bad impression from this scenario which may be the reason they might resist their votes.

Sir I think you missed 2 more points -

1> I think purchasing upvotes is also a similar practise
2> Some DTubers beg for UPVOTES/RESTEEM their videos, at the end of their videos THEY BASICALLY APPEAL FOR IT

These two things are my observations and must be stopped as well.

Thanks @clixmoney for taking a step forward about the topic, I pray your video would create some effect about the matter.
