One thing I noticed is that I can NEVER post a comment on another Wordpress blog ever again that has Askimet installed using a certain domain I own. I was using a software program called PR Backlinks Generator that allowed you to post comments on Wordpress blogs that are hosted on Wordpress.org. Unfortunately this software got me in more trouble than it actually helped. I just tried to post a comment on a Wordpress blog that WASN'T hosted on Wordpress.org and it still didn't allow me to comment. The best advice I can give you is to ONLY post up to 15 comments a day to keep yourself away from that. I was greedy and was posting about 50 to 100 comments. Now I have to pay the consequences.
