A risk assessment is not the same as a record of each decision.

You will need to assess the risk of people seeing something from one of those categories (for speciality forms, mostly low), think about algorithms showing it to users (again for forums thats pretty simple) Then have a mechanism to allow people to report offending content.

Taking proportionate steps to stop people posting stuff in the first place (pretty much the same as spam controls, and then banning offenders)

The perhaps harder part is allowing people to complain about take downs, but then adding a subforum for that is almost certainly proportionate[1].
