All my comments goes to Pending

Hi,

So I have been commenting before and all my comments have been approved directly on different sites. However a while a go something strange have happened.

Every time I comment, all my messages just never get approved directly. The webpage of many sites I comments on just reload. I did a test on my own site and same thing happened. it turned out every time I inputted my websites on the webadress form the msg never appears on any blog. But if I change the website adress to http://www.somethingelse.com , the msg get auto approved and get visible.

(I never write links on the editor textbox page, only in the assigned webadress form)

Now I am thinking maybe my website is blacklisted somehow. Anyone know why? How do I solve this?
