There are likely one of three reasons why your blog no longer exists:
Your content was deemed spam -
If you merely listed a bunch of keywords or you tried to sell medications online, we deleted your blog.
Your content was pornographic -
If there is no interstitial warning page in place and you posted pornographic media, we deleted your blog.
You linked to "dangerous" sites -
If you provided outgoing links to sites that are infected by malware or viruses, we deleted your blog.
Can you get your blog back?
Yes you can. Request in this forum that we reset your blog. Your blog will remain for as long as you continue to NOT violate one of the reasons listed above.
