Hello
Yes, it isn't a real name.
Yedaya Katsman is upstreaming those patches by me, under my permission,
and I forgot to tell him my name, so he took it from gitlab, which is just a nickname.
All of "SzczurekYT <szczurek@szczurek.yt>" should be replaced with "Kamil Gołda <kamil.golda@protonmail.com>",
this is my name and the e-mail I would like this to be under.
Excuse me for the chaos.

You need to use real names or real known identity.
