While a group of celebrites have launched campaigns seeking relief aid for earthquake-ravaged Japan, a distinct group of stars have surfaced on the negative side of the situation with misguided activity on the omnipresent microblogging site Twitter.

Celebs like 50 Cent, Gilbert Gottfried, and now the 'Family Guy' scriptwriter Alec Sulkin have sparked off a row with insensitive tweets on the disaster that has caused over 10,000 deaths and left Japan facing a potential nuclear crisis.

Alec Sulkin was latest to join the disgrace list with a tweet on the death toll of the Japan earthquake and the consequent tsunami.

If you wanna feel better about this earthquake in Japan, google 'Pearl Harbor death toll.'

He later deleted the tweet and apologized for it: Yesterday death toll = 200. Today = 10,000. I am sorry for my insensitive Tweet. It's gone.

Meanwhile, Gottfried has apologized for his tweet that led to his sacking. On Tuesday, the comedian tweeted, Sincerely apologize to anyone who was offended by my attempt at humor regarding the tragedy in Japan.

A second tweet read: I meant no disrespect, and my thoughts are with the victims and their families.

Gottfried lost his job as the voice of the Aflac duck due to his tweets.

Gilbert's recent comments about the crisis in Japan were lacking in humor and certainly do not represent the thoughts and feelings of anyone at Aflac, Michael Zuna, a senior VP and chief marketing officer for the insurance giant, said in a statement.

Aflac Japan - and, by extension, Japan itself - is part of the Aflac family, and there is no place for anything but compassion and concern during these difficult times.

Gilbert Gottfried
Gottfried lost his gig as the voice of the quacking duck for Alfac over a series of insensitive tweets on the Japan disaster, which included:"Japan is really advanced. They don't go to the beach. The beach comes to them.""I just split up with my girlfriend, but like the Japanese say, 'They'll be another one floating by any minute now.' "Interestingly, Gilbert Gottfried got support from a comedian colleague.Joan Rivers tweeted Tuesday: "Oh come on people-this is just outrageous!""Gilbert Gottfried was FIRED from Aflac for making jokes about the tsunami in Japan.""That's what comedians do!!! We react to tragedy by making jokes to help people in tough times feel better through laughter." Reuters
50 Cent
"Wave will hit 8am them crazy white boys gonna try to go surfing," he first tweeted on Friday morning.Later in the afternoon, he said, "Look this is very serious people I had to evacuate all my hoe's from LA,Hawaii and Japan. I had to do it. Lol."The tone later changed: "Nah this is nuts but what can anyone do about it. Let's pray for anyone who has lost someone."But the rapper was back to singing the same tune with a disclaimer, "Man they made a movie about all this 2012 now you think that was a lucky guess," 50 tweeted a few hours later. And to defend himself, he said, "Some of my tweets are ignorant I do it for shock value. Hate it or love it. I'm cool either way 50 cent." Reuters
