This userscript exists because someone needs to maintain the rules for Chinese and English users since swdyh's rules are mainly for Japanese websites. Don't be afraid of the fact that most feedbacks are in Chinese. I would like to add rules for English users if I could. Feel free to leave feedback.
To request rule, you should follow the following format
Title: [NSFW]Rule for www.example.com
NSFW: yes or no
Rule: (If you create one but fail, you'd better provide it to make life easier for me)
I won't spend time on writing rules for those who don't obey the rule.
The script is created for Firefox 57+/Chrome with Tampermonkey. Firefox(<56)+Greasemonkey should also work
Some websites like Google send the response with header 'x-frame-options', which blocks the creation of iframe. You can use header modifier like ModHeader for Firefox or Ignore X-Frame headers for Chrome to remove the header and make the script work for this website. Luckily, there aren't many websites like this.
The script doesn't support pixiv.net. For those who use Firefox, you can install weautopagerize and add the following line to the exclude URL in order to use them together
