If you get a direct message from one of your followers pointing you to a blogspot post where you “did something funny” I would advise not clicking it. I have gotten 3 of these so far and they redirect to a twitter fishing page. Much like the myspace facebook and msn ones that I have seen going around lately.
A good rule of thumb. If the domain is not the site you are going to i.e. its twitter.somerandomsite.randomdomain.h4x0ru.com and not twitter.com. Then dont put your login info in
