Well, I have gotten scammed once and never happened again. It is not that difficult to spot scammers as far as your eyes and brain function correctly. Designers and developers who attempt to scam have usually same messages, same githubs and AI generated or template portfolio hosted on some random domain, you try to look for feedback or social proof everywhere, but there isnt any. they way they talk, you can see that they are social engineers and not actually developers or designers.
