Don't worry about it. When you make substantive of specific comments that add information, it will be voted back up. Be sure to read the Guidelines - there's a link at the bottom of the page. Welcome.
Your comments are probably getting voted down for not adding much to the conversation and I think people probably felt like your one submission was spammy and off topic since a lot of the US based folks on here are probably wondering why it's significant and you did not provide much context.
