The site is completely broken
I have this problem https://learn.microsoft.com/en-us/answers/questions/1880292/many-error-500-for-2-days
(I cannot even comment in my own threads...)
And for rare threads where I can comment, I also see them only after hours (same for other people comments/answers, I just see "xxx has commented", but I see nothing)
....and tons of SPAMS, with a bot which answers... to SPAMS
Ridiculous
