It totally is. Make a profile with a Western-sounding, preferably female name, and submit a similar typo-fix PR. I can guarantee you that it will be accepted, or at the very least, not featured on a Twitter account called "Shitoberfest".
Minor typo fixes and such have been an established way to make a first bite-sized contribution to OSS projects. What changed this year that people are suddenly yelling at the top of their voices about the 30 (yes, thirty!) emails that they got this week?

These aren't minor "typo fixes".If you want to know how maintainers feel then read all of them.
I have made a genuine typo fixing PR and it was accepted by the repo. And yes, I don't belong to the group you refer to in your comment. I don't know what's happened with you or why you feel that way. It would be better to support your point with an example or an incident.
Do it 20k+ times and it very well may be. You appear uninformed about what is actually happening.
It's not the username in these examples that's the problem.
