I will say it is right and it is also wrong. It is right in the sense that, at time when someone post it doesn't receive vote between couple of hours. People might see the post and ignore because they will thing it not an interesting post that why it hasn't received any vote yet, not knowing everyone is ignoring because of that taught. But if u could at least give it one vote your self then when someone else sees it, that vote might motivate him/her to open the post to read and eventually also reward his post.
And I will also say it is wrong because it is also a way of being dishonest to the community. You should give a chance for people to vote for your work at least you spent so much time for it.Even if am to vote for my post I won't take the first place probably the last.
