I finally got a response from Sola:
Hello Peter,
The warning/restriction on your account was due to a post portraying nudity. Nudity in any form is not accepted on the platform.
It's considered as a violation of Sola TOS which is why the post had to be removed.
Good - so I won't waste my time with this shit. Someone recommended it to me, but I have better things to do .
Maybe slicing off heads of "Infidels" is permissible, just don't show any nudity. But it is not just radical Islamists - the entire USA and networks/platforms based in the USA have similar TOS. Yes, fuck them all! One TOS I read years ago (after a depiction of Michelangelo's David in one of my paintings was banned) even forbade the crack of an ass - so no pictures of plumbers are allowed!
You did a nice service for other, Peter. :)
