Some simmers don’t download CC because they are afraid of ads and viruses.
While the Custom content is virus free, some sites like to hide it behind link shortened which can contain adds that try to trick you.
The best way to bypass this is to use universal bypass an extension you can get for Firefox and possibly chrome.
With this you no longer have to suffer sites like addly short.st or bit.ly
Another great app is addblock plus which blocks some adds. This is available for both Firefox and chrome.
So get these too things and feel safer getting CC for the sims 4
