Thank you for your reply.

Minnowsupport doesn't charge SBD every time, although you have to pay a (very very little) amount to get a registration. That one is one of the good ones though!

I don't think the people behind those upvoting bots will leave Steemit on short term, but it might end someday and then they can cash out. It's a doomsday scenario ;).

You're right about Cheetah too, it does bring up similar content and the one thing that 'frustrates' (Sounds heavy but my feelings are way less) me is that it brings up your own content. Its something you wrote yourself so it shouldn't get the attention of Cheetah. Only when you copy paste from an other author or a source from internet.
