"wangduoyu666!.+-"
Whoops, this looks like username -> wangduoyu666 (same for "wangduoyu8", "wdy666666". Seems like they're incrementing numbers in username too, but probably false positives, maybe popular username)
Google it. Probably skid's github, linkedin, etc. (not verified)
And looks like OP missed this. Also name on telegram is fake of course, Wang Duo Yu is singer in China, so skid is using singer's name as username and also as a full name in Telegram.
Ps.: From their backup telegram, also "wangduoyu12"
Ps2: From OP write up -> https://t.me/wangduoyu0 -> there is youtube channel https://www.youtube.com/@duoyuwang4820 which links in description to this telegram channel wangduoyu0
And it's full of videos of someone making tutorials to bypass china firewall? etc. Multiple 30min-1hour videos, there must be treasure trove of info. Videos is leaking these gmail accounts: https://i.imgur.com/LUiKbF6.png
