it would be wise to check ones in awhile
http://bl.usefulscripts.com/ if your domain or email is listed there, alot of submitters dont have a cleu that maybe one or more of their domains is blacklisted.
Now why i am saying this: if you dont know you are blacklisted and also dont know the reason why, you will keep making the same mistake over and over again, most of your submitting will be waisted time. Wouldnt it be better to fix the mistake and get listed everywhere?
