A while back, they started aggressively rate limiting non-logged-in users.
I rarely login, because I don’t want to be a supply chain attack vector, but I guess that’s bad for someone’s promotion metrics.
Anyway, don’t host documentation there, and if you do, put it on one big page. If I read two paragraphs, think, then read the next page and so on, it bans me after about 5 clicks.
Them A/B testing “make it all private” would disappoint me, but not surprise me.
