when i ask something in the picture / say something the fact about the picture it just get invisible like it was mean harm to anyone and people just voting down my comment
I looked through your comments. They are mostly fine, though sometimes a bit silly. I think some get downvoted because of your very bad grammar. I won't say something like "learn English omg stupid" but pleasy try a little harder. Use Google translate or something. People hate bad English.
Well, people can vote some of your comments down for any reason, not just for being harmful. Also, out of your total 77 comments, you only have 5 or so downvoted, which is, I would say, about average. Not a thing to create a thread about.
