It seems odd to host works featuring rape and lolicon and rape+lolicon while purging works that merely use 'trap' in the title.
With proper tagging this kind of content can be avoided. Questionable language like this is harder to avoid, unless you avoid the whole category it's commonly used in. Although I guess one solution would be to tag these as well with archaic offensive terms
and leave them be, since other than the one word, which in no case is meant to offend in any manga uploaded to Dynasty (it would never have made it here in such a case), these are usually actually not bad stories at all.
