Remove convicted offenders from streaming platforms!

I was shocked and appalled to see that artists convicted of horrific crimes such as R Kelly, Rolf Harris, Gary Glitter and Lostprophets' Ian Watkins were all freely available on nearly all major platforms to stream and purchase. They have been convicted of sexual offences with minors. What sort of message is this sending out?
Are streamers unaware of their crimes? Why do they even have these platforms available. How would that make the victims' families feel? Do companies have zero morality that they still want to make a profit from peadophiles?

R Kelly - "The jury found Kelly, was the ringleader of a violent and coercive scheme that lured women and children for him to sexually abuse." (https://www.bbc.co.uk/news/entertainment-arts-58714203)

Rolf Harris - "Rolf Harris has been jailed for nearly six years for 12 indecent assaults against four girls - including one aged just seven or eight." Mr Justice Sweeney said Harris, 84, had taken advantage of his celebrity status and had shown "no remorse".

Gary Glitter - "Former pop star Gary Glitter has been jailed for a total of 16 years for sexually abusing three young girls between 1975 and 1980...was sentenced for attempted rape, four counts of indecent assault and one of having sex with a girl under 13."

Ian Watkins - "Lostprophets singer Ian Watkins has been sentenced to 35 years for a string of child sex offences including the attempted rape of a baby. Watkins, 36, from Pontypridd, pleaded guilty at Cardiff Crown Court last month to 13 child sex offences."

These are just four that I can think of - I am sure there are probably more.
