I agree with @steevc here.
I’ve never used an upvote service, or bought anything like that. I honestly wouldn’t know how to, but I know that doing that would generally hurt your reputation here. It’s definitely not the same as St**m.

If you want advice on how to get votes, I’d suggest you post your most honest and valuable work.
What are you good at? Like actually good at?
Write about what YOU care about and soon you will find others in communities that care about what you post about and will want to support you.
Get to know people, engage and things will happen.
You don’t need upvote bots to make a few quick $$$.

Hope that helps
