We published a statement on our stance on neutrality of free software (and why we won't stay neutral in this case): https://f-droid.org/en/2019/07/16/statement.html
"We believe platforms like F-Droid’s repository or fediverse instances must be moderated in order to prevent oppression and harassment to flourish." - this is wrong headed in the extreme.
It's not your business to dictate what people can and can't say online.
Your job is to be a neutral platform. If it's criminal, take it down. If not, you have no right - even if you don't like it.
