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.
Then make a stink about that and they’ll fix it. Most likely nobody tested if the system breaks when you have so many curators blocked (because honestly, who would have this many) and it’s a simple fix to do.
