It legitimately doesn't matter.
This seems to be a common talking point among those who oppose this forum's existence but it's not actually an argument— it's a pretty cheap way to attack the forum— to use an already abhorred internet subculture as a straw man of sorts.
If the argument is that by using the site you're supporting the work of incels (as I've heard someone say here)— SS clearly isn't for profit, and consequently the creators— even if they were still involved in the running of the site, which they aren't— don't benefit from its usage.
If the argument is that incels created this site and incels are misogynistic/homophobic so this site must be misogynistic/homophobic— well, that's demonstrably false. The rules clearly state that discrimination on the basis of gender or sexual orientation isn't allowed. I certainly haven't seen any misogynistic or homophobic posts here.
(Which, y'know, makes sense when you consider the forum's demographics. From polls— around half of the members are GSMs (the admin herself included). Around half are women. Around 75% are under 30, and young people tend to lean liberal, socially. Around 80% are either from North America or Europe, and the countries therein tend to have more favourable laws governing women's and LGBTQ+ rights relative to the rest of the world. It's hard to imagine most members with such backgrounds as proponents of incel ideology.)
So no, I don't think it should bother anyone.
