We have installed anti-spam software on our site and are actively monitoring users who post repeated spam comments. We value our readers’ different opinions and try not to intervene with the open discussions. However if we find the user repeated post the same message over and over again on the same article, we consider that spam and it makes our site less enjoyable for everyone. We hope to continue to keep our site open to all civilized discussions. Sometimes it is ok just accept not everyone will have the same opinion and point of view. Thank you all for supporting our site.
