You are right
I guess the persom who owns the account already spoke to some people by begging them to upvote his posts. Incase you do not know, people do this a lot and it is quite annoying.

Also, there are times that some people will mistakenly press the downvote botton. I won't lie, i have mistakenly pressed the botton.

Also, i feel like any article that is wrotten by someone is his creative work and it may take time to achieve that. Instead of downvoting the post because i do not like it, i will rather pass and go.

The only reason i downvote posts is when it does not pertain to what they mostly talk about it that community or it is totally meaningless.
