@neoxian,
That would be a great thing to raise an alert against his work! Yeah I have noted his work few months back! After reading your posts I have decided to use his upvote service and few time i sent $1 to them and got $0.8 worth upvotes! I have questioned it and they got kind of nice answer that I didn't understand!
You know I have no such SP to fight against that crime and if I do, we all know the outcome! So, I stopped using his f*cking upvote service! Seriously I hate people who show like they act genuine, but they are not doing things in genuine!
You can do nothing! I know you from the very first day in Steemit and trusting you and know how you are doing things! So, those are good lessons for all of us! And don't worry about your SP! I know it's huge, but sometimes we can use it in great purposes! Anyway glad you decide to share this fair warning!

Cheers~
