For 0, because this policy statement is vague:
For 1, Because clearer speech is officially suppressed:
“We will keep hiding and closing new topics that are created and if a user keeps creating topics about this even after an official warning their account will be closed.” Source:
So, F-droid has a forum policy, linked above, of forbidding writing certain words, sites, or app names. The full list is unknown. The result is a chilling effect.
Are you trying to get someone banned for writing forbidden words?! 
FWIW I only know of one app and site that were banned.
I hope it is safe to say FreeTusky used to be in F-droid, but was removed because of the controversy.
Finally, this sort of issue makes one wonder how many apps in F-droid explicitly control behavior or limit access to sites or information, because of developers’ political beliefs.
But yeah, I’d rather talk about nerdy app stuff too, and remember I didn’t start this thread, or write any forbidden words, hopefully.
