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.
Steam famously doesn’t have strict content guidelines. They don’t really remove anything from their marketplace (you can find unfettered racism and mass shooting simulators easily). Valve is very hands off when it comes to moderation, community, third games in a series or really anything.
