Baber has shut down claims of his death saying "its pretty upsetting" after speaking with WalesOnline in Cape Town, where he has landed to prepare for the next leg of the World Sevens Series.
"It isn't very nice at all to read that you have died," said Baber.
"It is mind boggling why someone would do this. I don't understand it."
"When you are away from family and travelling the world, you don't want people to hear that kind of thing... If a member of your family were to see it, it would be a terrible shock.
"I contacted my mum and the rest of my family to let them know I was fine," he said.
Cardiff Rugby Life also recently shut down the fake reports through Twitter which said they weren't sure why anyone would fabricate his death.

Details in the fake story reveal it was based on a genuine report from July, using details of the location, car, and the same name of the person who was killed in the fatal crash.
"Saying that about me is one thing," said the former Cardiff Blues coach.
"To think they have used someone else's name who has actually died is horrendous. It is sickening."
The fake report also contained biographical information about the 45-year-old Baber who played for Cardiff, Pontypridd, Oxford University, Aberavon, Bristol and the Dragons before becoming a sevens coach.
The story was the third erroneous report related to Fijian rugby to have appeared online in the past couple of years.
In 2016 a fake news story reported about Baber's predecessor as a national sevens coach, Ben Ryan.
Then earlier in the year Fiji's test captain Akapusi Qera was said to have died after collapsing during training.
