New users, especially people posting in #nudesformastodon: I recommend you don't post again until after you've read the mastodon.social site rules, which you can find here: https://mastodon.social/about/more
Specifically, you're not allowed to post nude or sexualized images without using the "sensitive image" overlay (the "eye" icon that appears after your image is uploaded).
Breaking the rules will lead to revocation of your ability to post to public timelines or suspension of your account.
Thanks!
Block and suspend them all!!!
