I think it is better to keep your example and usually avoid using vote buying services. If you want/need to use it one time to really promote a single post, I think that is valid.
But we need examples like you that MAY sway the opinion and the majority of steemit users to do the right thing. I didn't mind giving you a $0.30 upvote just now. I know what you do is good. But if you start vote buying I maybe will give a token 5% upvote. And maybe I am not alone. So, I think you are doing better by NOT vote buying.
Yeah, winter depression is a bttch. I get it sometimes too.
Take care! Love your work with OCD!
And keep on Steemin On!
Thx
