I reported them for harassment with the following statement:
The purpose of this group is to review bomb any game that has gay representation. Their discussion threads talk about using other platforms to discriminate against LGBTQ+ communities and individuals to circumvent Steam's TOS policies. This type of behavior promotes discrimination, review brigading, and toxicity. It is surprising Steam is tolerating such open homophobia on this platform.
I have "until then" I'm just finishing my current pile of books before I move onto another VN, good to know it's probably going to be good as this loser hates it.
