Not exactly true, you get warning points and based on the amount of points a member has would determine if they get banned or not.
Also I totally see your point, but also this website isn't exactly sponsored by the catholic church. It's a website that hosts threads dedicated to sharing naked pictures. Your dedication to the rules is admirable but at the same time your speech is a tad hypocritical don't you think?
There is no clear permission from most of the people's whose content is being shared here, and a lot of them even have onlyfans or other watermarked media indicating a copyright so in theory anyone who signs up to be a member here is doing so willingly and under the understanding that rules will be broken or the site would cease to exist due to lack of content.
What is it about someone adding themself to the do not post list that puts them in a different position than someone who marks their content with copyright? Sharing the content no matter if they are on the do not post list or not is still a violation of their copyright. So what makes it ok for you to share/collect copyright material but then turn around and try to shame someone here for asking to do exactly what you are doing? The do not post list is a RULE from this website only, but the copyright is a LAW everywhere.
