This morning, I found my blog as being redirected to a domain parking website. further investigation showed that the culprit was advertlet domain being redirected for domain expiry. So off advertlet go from my template.
I mean I wouldn't trust a company that can't afford to keep track of their own domain expiry to keep track of how much I make from advertisement. No emails from advertlets to explain this matter what so ever even when the problem started from January 5th.
