Nothing past PG13 will survive long in the critique sections. There are minors here, and this website is not flagged by parental control services as an adult website, so the content needs to stay within the defined parameters.
Putting a warning label up that it’s a bit rough, has a bit of language, etc. is fine, but if it’s way over the line, it will still be removed.
The idea about adult content has been discussed, but the general response from WD is that, while it is viable work with a legitimate genre, there are plenty of other sites for that type of material and that it’s not something that will be hosted here.
