I am a link builder and do blog commenting. But from last few weeks I am not able to post comment on sites. I have done many research about this question but I didn't get answer anywhere.
When I post a comment on site (except blogspot) and press submit button this page redirect on the same page with no text like: "link submitted or Link awaiting approval" notification.
One thing I have that wordpress may blocked my IP address but another system of my network are able to post comments on the same site.
If you have face this problem or you know the problem solution then please help me.
