Hi, @laddawan, I will write in English to save some time. I just find your reply and want to tell you sure there are no written rules about it. But I communicate a lot about it, when you are upvoting yourself the money doesn't benefit the community. How does it start, it was with one of your posts we send to the US for it to be upvoted (today the Thai community doesn't have enough to go by itself) and they refuse your post because you are upvoting yourself and it don't help the community growing and a rule for new communities was told. No help for users upvoting themselves so this is where it comes from. So it is up to you to do what you want, help your community or upvote yourself. As I tell before you are part of Thai community and we love you.
