I sold all my sbi shares as it I see it as some kind of bid bot service, except you get the returns over a long period rather than in one post.
I'm not downvoting anyone who uses it yet though as I believe it's helped with onboarding and retaining users but it's a grey area. I've seen posts that have blatant plagiarism being upvoted by sbi and I'll start downvoting if I see things like this happening. Also seems sbi just upvotes blindly regardless of length or quality of post - have also seen 20 word "shit posts" get more from sbi than others who have written much more in depth...
Jury's out
