You assume the scammers want everyone to fall for this trick.

The reality is different - they leave these huge red flags so that people who aren’t very bright or careful will fall for it.

That is the same reason why scammers put spelling mistakes in emails - not because they don’t know how to use spellcheck, but because they want to filter out those who would spot these mistakes.

They want to scam careless, gullible, „stupid“ people, not someone who is careful enough to spot security red flags.
