IRLRosie is an awesome scambaiter. She is a voice actor which makes her videos all the more fun. Her Alexa impression is my absolute favourite but she can also do a mean Siri one too.
Her YouTube channel (which you can find at https://www.youtube.com/user/rosieokumura) features all the old favourites including tech support scammers, IRS scammers, sweepstakes scammers and many more.
Check her out but be warned, your sides will hurt from laughing!
