There's r/foreveralone. I don't know how the community evolved, but like 7 or so years ago it was basically what you described. People seeking comfort over feeling undateable and being scared of never finding anyone, but without the toxicity and hate that incels are known for.
Don't ask me how I know this.
Yes, I came here because I noticed the same problem with [email protected]
I also found two older posts here describing the same problem:
Post 1
Post 2
It seems like a random problem
Account 1 - 3 can't access FOSS, but 4 can.
Account 4 can't access Bready, but 2 can.
Oldest notice of this problem is 29 days old, I hope it gets fixed soon.
