Do we like Diamond Platnumz?
Our score: 5 out of 10. A big career and no harmful words of his own turned up, but there's one contested political endorsement, an unanswered allegation, and not much verified good to set against them.
Naseeb, sorry, Nasibu Abdul Juma Issack, born 2 October 1989, is the bloke the world knows as Diamond Platnumz. He came out of Tandale in Dar es Salaam, put out his first album in 2010, and built that into WCB Wasafi, a record label that now also covers a film company and TV and radio stations. He's the highest-selling Tanzanian artist going, with Channel O, MTV and Kora wins on the shelf.
The fresh mess is in Australia. His management says the Perth (10 October) and Melbourne (11 October) shows of the Retro World Tour were cancelled after a dispute between promoters over collecting and splitting ticket money, with 4,452 tickets sold. Management says it flew him to Perth at its own expense and is still waiting on the balance of his fee. So the fans got stung, but the account here is management's, and we haven't seen the promoters' side.
Politics is where the harm test gets interesting. On election day in October 2025, he posted a long Instagram tribute to President Samia Suluhu Hassan and pledged that he and the institutions he leads would vote for her. Citizens who see her government as intolerant of dissent piled into his comments and threatened a boycott, and he deleted the posts the next day. Where you land depends on whether you read it as a celebrity backing the incumbent or as cosying up to power.
On the other things the harm test looks for, the record is quiet. In 2019 he spoke in Berlin about xenophobic attacks on African migrants in South Africa and said “Africa doesn't need this.” We found no anti-LGBTQ+ campaigning, no conspiracy theories and no climate or vaccine nonsense in his own words. Be aware, though, that a lot of English-language coverage of him is Kenyan gossip, and we couldn't find much on what he thinks about trans or gay rights either way.
On how he treats people, the main item is old. In 2020 the actress Wema Sepetu told a Tanzanian tabloid, Ijumaa Wikienda, that he was physically abusive during their on-and-off relationship in 2012 to 2014. That is an allegation only, the report said he had not yet responded, and we found no court case. It isn't a pattern we can prove, but it isn't nothing either.
He's also had a run-in with the regulators. In late 2018 Tanzania's arts board, BASATA, banned him and Rayvanny from performing after they defied its orders over a banned song. They posted a video saying they sometimes mess up “as we are also human beings,” and the ban was later lifted. That's a spat about content rules, not about hurting anyone.
